(a)
Interpretation:
The conversion of the given starting material to the indicated nitrile is to be shown.
Concept introduction:
Nitriles are considered as acid derivatives because they hydrolyze to carboxylic acids. They are made from carboxylic acids by conversion to primary amides followed by the removal of water. The reduction of nitrile by lithium aluminium hydride gives a primary
(b)
Interpretation:
The conversion of the given starting material to the indicated nitrile is to be shown.
Concept introduction:
Nitriles are considered as acid derivatives because they hydrolyze to carboxylic acids. They are made from carboxylic acids by conversion to primary amides followed by the removal of water. The reduction of nitrile by lithium aluminium hydride gives a primary amine and the reaction with that of Grignard reagent gives an imine that hydrolyzes to a ketone.
