Chapter 8, Problem 25E

A useful solvent that will dissolve salts as well as organic compounds is the compound acetonitrile, ${\text{H}}_{\text{3}}\text{CCN}$. It is present in paint strippers.

(a) Write the Lewis structure for acetonitrile, and indicate the direction of the dipole moment in the molecule.

(b) Identify the hybrid orbitals used by the carbon atoms in the molecule to form $\sigma$ bonds.

(c) Describe the atomic orbitals that form the n bonds in the molecule. Note that it is not necessary to hybridize the nitrogen atom.
