Vedclass · Answer

(C) The reaction sequence is as follows:$1$. Oxidation of the secondary alcohol $1	ext{-phenylbutan-2-ol}$ with $PCC$ (Pyridinium chlorochromate) yields the ketone $A$,which is $1	ext{-phenylbutan-2-one}$ $(CH_3CH_2COCH_2Ph)$.$2$. The reaction of the ketone $A$ with hydrazine $(H_2N-NH_2)$ forms the hydrazone $B$,which is $1	ext{-phenylbutan-2-one hydrazone}$ $(CH_3CH_2C(=NNH_2)CH_2Ph)$.$3$. The subsequent treatment of the hydrazone $B$ with $KOH$ in ethylene glycol at high temperature is the Wolff-Kishner reduction,which reduces the carbonyl group to a methylene group,yielding the alkane $C$,which is $1	ext{-phenylbutane}$ $(CH_3CH_2CH_2CH_2Ph)$.Thus,the correct sequence is $A$: $1	ext{-phenylbutan-2-one}$,$B$: $1	ext{-phenylbutan-2-one hydrazone}$,$C$: $1	ext{-phenylbutane}$.

The products $A$,$B$ and $C$ in the following reaction sequence are:
