$CH_3-CH=CH-CH_2-CH_2-CHO$

Vedclass · Answer

(C) The reagent $AlH(i-Bu)_2$ is Diisobutylaluminium hydride,commonly known as $DIBAL-H$.$DIBAL-H$ is a selective reducing agent that reduces nitriles $(-CN)$ to aldehydes $(-CHO)$ upon hydrolysis.In the given reaction,the nitrile group $(-CN)$ is converted to an aldehyde group $(-CHO)$ while the double bond $(C=C)$ remains unaffected.Therefore,the reaction is: $CH_3-CH=CH-CH_2-CH_2-CN \xrightarrow[	ext{2) } H_2O]{	ext{1) } DIBAL-H} CH_3-CH=CH-CH_2-CH_2-CHO$.Thus,the correct option is $C$.

What is $A$ in the following reaction?
$CH_3-CH=CH-CH_2-CH_2-CN \xrightarrow[\text{2) } H_2O]{\text{1) } AlH(i-Bu)_2} (A)$
