Vedclass · Answer

(B) $(I)$ Aldehydes and ketones that are less sterically hindered at the carbonyl carbon show a higher rate of nucleophilic addition reaction.$(II)$ The presence of electron-donating groups at the carbonyl carbon decreases the electrophilicity of the carbon atom,thereby decreasing the rate of reaction.$(III)$ Comparing the given compounds: $CH_3 CHO$ is an aldehyde with the least steric hindrance and the least number of electron-donating groups attached to the carbonyl carbon.$	herefore$ Nucleophilic addition reaction will be most favoured in $CH_3 CHO$.

Column-$1$ (Reaction)	Column-$2$ (Product)
$A$. Benzaldehyde + $Zn-Hg/HCl$	$I$. Cyclohexanol
$B$. Benzoyl chloride + $H_2/Pd-BaSO_4$	$II$. Benzyl alcohol
$C$. Cyclohexanone + $NH_2NH_2/KOH$	$III$. Toluene
	$IV$. Benzaldehyde
	$V$. Cyclohexane
