We have that the bond angles that are closest to the actual values for the h-n-c and o-c-o bond angles are
Generally, In H-N-C bond nitrogen has Sp3 hybridization, it will have the angle 109.5 degrees.
In O-C-O bond C atom has sp^2 Hybridization so it will have the angle by 120 degrees.
Therefore,bond angles that are closest to the actual values for the h-n-c and o-c-o bond angles are
