In a hydrogenic atom, s- and p-type orbitals of the same shell
are degenerate. Explain why the 2s and 2p
orbitals would not be degenerate in a carbon atom, and justify
their relative energy ordering. (Hint: consider
the radial distribution functions for these orbitals).
Identify the hybrid orbitals on all atoms in the molecule
CH2O.
The H atoms in CH2O contain the following hybrid
orbital.
The C atom in CH2O contains the following hybrid
orbital.
The O atom in CH2O contains the following hybrid
orbital.
1. Describe the antimony pentachloride. What type of hybrid
orbitals form?
2. A molecule has a central atom surrounded by 1 lone pair and 5
atoms. The best description for the shape of the molecule is: A)
trigonal planar B) Square Planar C) See-saw D) Octahedral E) Square
Pyramidal
3. True or False: Bond formation tends to decrease the potential
energy of the two atoms involved in forming the bond.
1. PF5 has five single bonds to the central atom. SF4 has four
single bonds to the central atom and the central atom possesses a
lone pair of electrons. How can this observation be used to explain
the different bond angles you measured.
A.) Draw a Lewis diagram for SO42- in
which the central S atom has a formal charge of zero and show all
NONZERO formal charges on all atoms.
B.)Draw a Lewis structure for SO42- in
which the octet rule is satisfied on all atoms and show all NONZERO
formal charges on all atoms.
C.)Based on formal charge, what is the best Lewis structure for
the ion? Octet rule or smallest formal charge
