Description

Problem(Set(11(–Bonding! Chem!105! 1. (a) What is a chemical bond? (b) Why do atoms form bonds? 2. Define the following types of bonds: a. Ionic b. Covalent A) polar covalent B) non-polar covalent c. Metallic 3. (a) Define electronegativity in your own words. (b) How can we use electronegativity to predict whether a bond between two atoms is likely to be covalent of ionic? 4. What type of bonds are expected in the following materials? a) Oxygen (O2) b) NaCl c) H2O d) Diamond (pure carbon) e) Methane (CH4) f) Tin g) Iodine (I2) h) Carbon monoxide i) NO2 j) Mercury 5. The compound COCl2 has been used as a chemical warfare agent (phosgene). It and two similar compounds, COBr2 and COI2, are all eye irritants and cause skin to blister. The severity of the skin reactions is influenced by the polarity of the compounds. Rank the compounds in order of increasing polarity of their carbon-halogen bonds. 6. Among the diatomic molecules detected in interstellar space are CO, CS, SiO, SO, and NO. Arrange the molecules in order of increasing polarity....
