ASK YOUR TEACHER   Choose the selection which correctly identifies the sets of hybrid orbitals used by central atoms to form bonds in both of the molecules and/or ions whose formulas are given below: HCN and NO2- a) The central atom of HCN uses sp hybridization and the central atom of NO2- uses sp2 hybridization. b) The central atom of HCN uses sp hybridization and the central atom of NO2- uses sp hybridization. c) The central atom of HCN uses sp2 hybridization and the central atom of NO2- uses sp2 hybridization. d) The central atom of HCN uses sp3 hybridization and the central atom of NO2- uses sp hybridization. e) The central atom of HCN uses sp hybridization and the central atom of NO2- uses sp3 hybridization.

Consider a molecule AB3, where both element A and B have 7 valent electrons.  Predict the shape and bond hybridization of the molecule.  Your answer should follow the format: a) number of total electrons for bonding; b) Steric Number and Lone Pairs; c) name of shape based on the VSEPR chart, c) bond hybridization.

What is the hybridization of each atom in the following molecules? (Do not include hydrogen atoms.)

Molecular orbitals are formed from linear combinations of atomic orbitals. Which of the following hybridizations could be involved in the complete molecular orbital configuration of homonuclear diatomic species?

Each of the structures for ClOCl, NCOH, and ClNO has atoms connected in the order given in their formulas. Identify the type of hybridization for the central atom in each compound.

2) a) Consider the following molecule . Given what you have learned about hybridization theory, draw an image or images explaining the bonding situation in this molecule. I want you to draw out all of the orbitals, hybrid orbitals and how they overlap to form the bonds in the molecule. Indicate the % s or p character in the given atomic and hybrid orbitals. Which C-C bond or bonds are the longest? In a paragraph or so explain the image or images you just drew. b) Lastly, consider the molecule below. Indicate the Molecular formula, the molar mass, label the hybridization of each atom except for hydrogen, indicate any chiral centers with a *, which bond or bonds are the shortest, identify by name of each functional group with an arrow pointing to the group.
