Answer 2

Trimethylamine is sp3 hybrid while formamide is sp2 hybrid.

Explanation:

• Trimethylamine is the compound with formula (CH3)3N.

• It has three bonds with three methyl groups and one lone pair.

• So this compound is sp3 hybrid.

• In case of formamide, it's apparent that nitrogen is again sp3 hybrid because it has one lone pair and three bonds - two with two hydrogen and one with the carbon.

• But the lone pair in nitrogen is donated to the vacant orbital of oxygen which is the electrophilic centre of the atom.

• So the nitrogen now has only 3 bonds, which become sp2 hybrid.
