Vedclass · Answer

(D) The conversion $CH_2=CH-CH_2-CHO 	o CH_3-CH_2-CH_2-CH_2OH$ involves the reduction of both the carbon-carbon double bond $(C=C)$ and the aldehyde group $(-CHO)$. $LiAlH_4$,$NaBH_4$,and $Na + C_2H_5OH$ are selective reducing agents that reduce the aldehyde group to a primary alcohol but do not reduce isolated $C=C$ double bonds. Catalytic hydrogenation using $H_2 / Ni$ (or $Pt/Pd$) is the appropriate method to reduce both the alkene and the aldehyde functional groups to an alkane and a primary alcohol,respectively.

Appropriate reducing agent for the following conversion is:
$CH_2=CH-CH_2-CHO \to CH_3-CH_2-CH_2-CH_2OH$
