Re: polydentate

monodentate is a ligand that binds in one place to the transition metal. Polydentate is a ligand that binds in more than one place to the transition metal.

Re: reason for hybridization

Hybridized orbitals have less energy than the unhybridized orbitals. The compound is more stable when hybridization occurs.

Re: Bond Angles

In regards to bond angles affected by electron electron repulsion, we don't need to know the exact angles of those angles. Just know that repulsion reduces bond angles.
