Answer the following questions about acetonitrile (CH3C = N:).

a. Determine the hybridization of both C atoms and the N atom.
b. Label all bonds as s or p.
c. In what type of orbital does the lone pair on N reside?
d. Label all bonds as polar or nonpolar.


Expert Answer

Step 1

Hybridization of carbon and nitrogen atom has to be given.

Hybridization is the mixing of valence atomic orbitals to get equivalent hybridized orbitals that having similar characteristics and energy.

Given, Acetonitrile H-C-CEN : I-U-I

Step 2

CH3 Carbon atom is Sp3 hybridization,

CN Carbon atom is Sp hybridization and

CN Nitrogen atom is Sp hybridization.
