The general order of reactivity of carbonyl compounds towards nucleophilic addition reactions is
- \[\begin{array}{l} \mathrm{H}_{2} \mathrm{C}=\mathrm{O}>\mathrm{RCHO}>\mathrm{ArCHO} \\ >\mathrm{R}_{2} \mathrm{C}=\mathrm{O}>\mathrm{Ar}_{2} \mathrm{C}=\mathrm{O} \end{array}\]
- \[\begin{array}{l} \mathrm{ArCHO}>\mathrm{Ar}_{2} \mathrm{C}=\mathrm{O}>\mathrm{RCHO} \\ >\mathrm{R}_{2} \mathrm{C}=\mathrm{O}>\mathrm{H}_{2} \mathrm{C}=\mathrm{O} \end{array}\]
- \[\begin{array}{l} \mathrm{Ar}_{2} \mathrm{C}=\mathrm{O}>\mathrm{R}_{2} \mathrm{C}=\mathrm{O}>\mathrm{ArCHO} \\ >\mathrm{RCHO}>\mathrm{H}_{2} \mathrm{C}=\mathrm{O} \end{array}\]
- \[\begin{array}{l} \mathrm{H}_{2} \mathrm{C}=\mathrm{O}>\mathrm{R}_{2} \mathrm{C}=\mathrm{O}>\mathrm{Ar}_{2} \mathrm{C}=\mathrm{O} \\ >\mathrm{RCHO}>\mathrm{ARCHO} \end{array}\]
Answer
(A) array l H _ 2 C = O > RCHO > ArCHO > R _ 2 C = O > Ar _ 2 C = O array
