Chemistry - Carbonyl compounds Question with Solution | TestHub

It is nucleophilic addition whose reactivity depends upon the electrophilic character of carbonyl carbon and steric hindrance only. Hence, the order of ease of the reaction would be

$\begin{array}{cc}\text{H}\text{C}\text{H}\text{O}>& \text{C}{\text{H}}_3\text{C}\text{O}\text{C}{\text{H}}_3>\\ \left(\text{A}\right)& \left(\text{B}\right)\end{array}\begin{array}{cc}\text{P}\text{h}\text{C}\text{O}\text{C}{\text{H}}_3>& \text{P}\text{h}\text{C}\text{O}\text{P}\text{h}\\ \left(\text{C}\right)& \left(\text{D}\right)\end{array}$
