In the reaction sequence CH3CH2Cl a0--NaCN-- X a0--Ni/H2-- Y a0--acetic anhydride-- Z, what is the compound Z?

Question

In the reaction sequence CH3CH2Cl a0--NaCN--> X a0--Ni/H2--> Y a0--acetic anhydride--> Z, what is the compound Z?

Accepted Answer

CH3CH2CH2NHCOCH3. CH3CH2Cl + NaCN -> CH3CH2CN (X). Ni/H2 reduces the nitrile to the primary amine CH3CH2CH2NH2 (Y). Acetic anhydride acetylates this amine to give CH3CH2CH2NHCOCH3 (Z, N-propylacetamide).
