Practice problem 21.82 nitriles undergo alkylation at the α position much like ketones undergo alkylation at the α position. the α position of the nitrile is first deprotonated to give a resonance-stabilized anion (like an enolate), which then functions as a nucleophile to attack the alkyl halide. draw the mechanism described above for the transformation below (propyl chloride will be the rx in this reaction).

Give the orbital configuration of the phosphorus (p) atom.
