CHE 152/Molecular Science I

Fall 2021

Office hours: Professors D. Amarante and F. Raineri will hold online Zoom Meetings at the times indicated above. These meetings are accessed through the Zoom link in the course’s “.CHE 152.01” Blackboard site. Also, if you prefer, please direct any questions you might have about concepts or problem solving by email to the course account [email protected]. Three grad TAs and several undergrad TAs will be helping us teach the course. They will also hold online Zoom office hours throughout the week, at specific times to be determined in the first week of classes. Where to direct your questions?: General questions about the course should be directed to the specially created General Questions Forum in Blackboard’s (“.CHE 152.01”) Discussion Board. In this way we can avoid relatedly answering the same question and everyone can benefit from the information. Questions of a more personal nature should be sent by email to the faculty email addresses [email protected] or [email protected]. When necessary we can also schedule a person-to-person Zoom meeting to further discuss any concerns you are having with the class.

Please be aware that all course correspondence will be direct to your Stony Brook email address.

Part 2: Course Delivery Mode and Structure

Most of the course activities and materials will be posted in the Oscer website for the course, that you can access at https://organic.cc.stonybrook.edu/che152-21/ The exceptions will be: ECHO360 recordings of the lectures, weekly online Quizzes, and the General Questions Forum, which can be accessed in the Blackboard website for the course with access at https://it.stonybrook.edu/services/blackboard and then select the “-CHE 152-01” entry.

Course Delivery Mode and Structure: The course consists of the following components: A. Lectures. MWF 11:45 AM – 12:40 PM, in Frey Hall 100. 1. These lecture classes will be recorded and streamed live; afterwards the recordings will be posted under the ECHO360 link in the Documents folder of the Blackboard site. 2. For each of the lectures there will be an Oscer pre-lecture quiz launched sometime in the afternoon before the lecture and ending at 11:00 AM in the morning of the lecture. 3. The lectures will include student participation through the online application Oscer Click that you can use with your phone or notebook. Please notice that your participation in class will count towards your final grade. 4. The PowerPoint slides used in the lecture delivery will be posted, under the “Lectures” menu item in the Oscer Home Page for the course. B. Workshops. On Thursday 8:45 AM – 11:05 AM (R01, R02, and R03) or 11:30 AM – 12:50 PM (R04, R05, and R06), in Frey Hall 119. The weekly workshops focus on problem-solving activities on the topics of the week. Students will work in groups of 5 members that will be arranged by the faculty before the first Workshop. The workshop activities will be posted in Oscer, where students will check for attendance to the workshop and the group will upload the solutions to the problems. Grad and undergrad TAs will be available to provide the students assistance

and to help with the class discussions. Attendance and solutions to the problems will contribute to the final grade in the course. C. Weekly Quiz. Multiple choice online quiz in Blackboard launched every Thursday at 3:00 PM (eastern time). The due date for each quiz is on Sunday of the same week at 11:59 PM (eastern time). The Quizzes are delivered with the Test facility of Blackboard, and they become visible at 3:00 PM every Thursday in the appropriate quiz folder Assignments/Quizzes/Quiz #. Two attempts per question are allowed. Detailed solutions for the problems in the quiz will be posted the following week. D. Homework. There will be three sets of homework problems due at 11:59 PM of the Friday of the week before each of the midterms. Students will submit each homework solution by email (as a single pdf file attachment in an) to the course’s email account [email protected].

Technical Requirements: General: you should have a standard computer system (desktop or laptop) with sufficient memory (minimum 8 GB RAM) and capable internet connection to comfortably operate with Oscer and Blackboard: upload and download pdf (and occasionally other generic file type) files. You should be aware that in case of technical difficulties you make contact the University technical help division: • •

Phone: 631-632-9800 (client support, Wi-Fi, software and hardware) Submit a help request ticket: https://it.stonybrook.edu/services/itsm

Your computer system and/or peripherals should also include camera and microphone, so that you can participate in synchronous Zoom meetings (workshops and office hours). If the specs of your computer system are not sufficient you can consult the site https://www.stonybrook.edu/commcms/studentaffairs/studentsupport/ for the possibility of accessing a laptop by loan. Helpful for Exams and Assignments: For exams and assignments involving problem-solving, you will be mostly using “handwriting with pen and paper”. When done you will have to submit your work. To do that, we recommend that you use your phone to photograph or scan the work and assemble several pages into a single pdf file. This is not mandatory, as you still will be able

to submit your work in the form of photographs taken with your phone, but it would streamline and speed-up enormously the grading work on our side.

Part 3: Course Learning Objectives Learning Objectives: Upon the completion of the course: 1.- You will be able to recognize and interpret the fundamentals of atomic and molecular structure, as well as predicting molecular geometries and how atomic orbitals interact with each other to generate molecular orbitals. 2.- You will be able to recognize the behavior of gases at low pressure, and to perform calculations by manipulating the ideal gas equation of state. 3.- You will be able to recognize and differentiate between bonding models when applied to simple organic and inorganic molecules. 4.- You will be able to name and (based on the coordination number of the central transition metal) to elucidate the geometry and isomers of coordination complexes. You will also make use of crystal field theory to predict the magnetic, spin, and spectroscopic properties of complexes of different molecular shape. 5.- You will be able to apply the concepts of chemical equilibrium and equilibrium constant expressions to the study of the acid/base properties of aqueous solutions, including their use in to understand buffer solutions and acid/base titrations. 6.- You will be able to recognize and differentiate the role of the components of a galvanic cell, and how those components interact together to make a device capable of performing useful work. You will learn how to use the Nernst equation to predict the directionality of oxidationreduction reactions. 7.- You will be able to recognize, differentiate, and implement the methods of chemical kinetics: how to use rate-law equations in both differential and integrated form, what is the role of the rate constants in these equations, and what are the consequences of their dependence with the temperature. 8.- You will be able to recognize the constituent parts of multiple-step reaction mechanisms and to apply the concepts and tools required for their analysis: elementary reactions, reaction intermediates, catalysts, rate-determining step, the prior-equilibrium approximation, and the steady-state approximation.

9.- You will be able to recognize how a variety of physicochemical properties (vapor pressure of the solvent, solubility of gases, colligative properties) of a dilute solution depend on its composition.

How to Succeed in this Course: i)

ii)

A very important aspect of successfully taking a course is managing well your schedule and keeping up with the development of the course and its deadlines. Please access the Oscer and Blackboard sites at least once a day to check for announcements and deadlines (as specified in the syllabus). Equally important is to keep track of the occasional announcements or instructions sent by email to your Stony Brook account. It is crucial that when dealing with solving problems you try to solve the problems by yourself, focusing on the reasons why all steps are taken, as opposed to memorizing the procedures for each problem. Problems may be formulated in an infinite number of ways, making it impossible to memorize all possibilities. You need to be able analyze the information and question in a problem and find by yourself the way towards the solution.
