Description

PROJECT 1 1. SYNTHESIS OF H3BCO a. Hyperconjugation is the process of stabilizing interaction that is from the interaction of the electrons in a σ-bond that is next to an empty or partially filled p-orbital or a π-orbital. This increases stability of the system. Negative hyperconjugation is the process of stabilizing interaction that is from a filled p-orbital or π-orbital to stabilize the molecule, increasing electron density of the σ-bond. b. The paper that identified the synthesis of H3BCO was Carbonyl Compounds of Boron and Their Isomers by Anne Skancke,and Joel F. Liebman. In this article it discusses that it is likely because of the low activation barriers may be cause for its instability rather than its thermodynamics of H3BCO c. The calculated bond length of BC in H3BCO is 1.55Á and the strength of the bond is 25 kcal/ mol. This was discussed in an article titled Carbonyl Compounds of Boron and Their Isomers by Anne Skancke,and Joel F. Liebman. 2. ACTIVATION a. A catalyst is a substance that increases the rate of reaction by decreasing the activation energy, but is not consumed by the reaction. b. Ammonia Is difficult to activate by transition metals because ammonia creates Warner complexes, and these require a lot of activation energy. .E–H Bond Activation of Ammonia and Water by a Geometrically Constrained Phosphorus(III) Compound Dr.  Thomas P.

The phosphorus is t-shaped because of bonding geometry. The phosphorus is connected to 3 other atoms and lone pairs. The lone pair has more repulsive than an atom would and causes the bond angles to be less that 109.5 degrees d.
