True or False
1. The presence of at least one lone pair on a molecule (with polar bonds) will make the molecule polar.
2. The geometry of a molecule is explained by the valence bond theory.
3. In valence bond theory, the bonding orbitals are spread over the entire molecule.
------------------------------------------------------------------------------------------------------------------
4. Which one of the following is INCORRECT?
a) if two 1s (atomic) orbitals form molecular orbitals. they would form two bonding orbitals.
b) Bonding molecular orbitals are lower in energy than their parent atomic orbitals.
c) Valence Bond theory cannot explain the extended pi bonding in a resonance structure.
d) Valence bond theory is based on the idea that bonds are formed from the overlap of atomic orbitals.
e) All the the above are correct.
