Question 2
Consider the molecule below and answer the question for the numbered atom cited. Please note that lone pairs have been omitted for simplicity, but all atoms except hydrogen obey the octet rule.
What is the hybridization of the nitrogen atom (marked as #1 on the diagram)?
The nitrogen atom (#1) in the molecule is bonded to three other atoms (two carbons and one hydrogen) and has no lone pairs. This leads to a total of four regions of electron density around the nitrogen atom.
The hybridization of an atom with four regions of electron density is sp3. Therefore, the nitrogen atom in this molecule is sp3 hybridized.
