Faster Examples:

What is the hybridization on each “central” atom (Ns and C)?

What orbitals from each atom is each bond formed with?Each nitrogen hydrogen bond (they all happen to be the same here)?

Each carbon nitrogen bond (they all happen to be the same here)?

The carbon oxygen bond?

Faster Examples: What is the hybridization on each “central”, what is each bond formed with?
