The reactivity of carbonyl compound towards nucleophilic addition of Grignard's reagent depends on extent of steric hindrance at

α

-carbon. Greater the steric hindrance smaller the reactivity. Hence, reactivity order is

II C H_{3} C H O > I C H_{3} - CO - C H_{3} > III P h - CO - P h

Q. When benzene sulphonic acid and p-nitrophenol are treated with $N a H C O_{3}$ , the gases released respectively, are

$S O_{2}, N O_{2}$

$S O_{2}, NO$

$S O_{2}, C O_{2}$

$C O_{2}, C O_{2}$

The reactivity of carbonyl compound towards nucleophilic addition of Grignard's reagent depends on extent of steric hindrance at $α$ -carbon. Greater the steric hindrance smaller the reactivity. Hence, reactivity order is
$II C H_{3} C H O > I C H_{3} - CO - C H_{3} > III P h - CO - P h$
