Question

What is the correct order of the rate of alkaline hydrolysis of these esters? CH3COOCH3[.rate=r1]. , CH3COOC2H5[.rate=r2]. , CH3COOC3H7[.rate=r3]. (A) r1>r2>r3 (B) r1 < r2 < r3 (C) r1 < r2>r3 (D) r1>r2 < r3

r1>r2>r3 , Rate of hydrolysis decreases with increase in size of alkyl group

Q. What is the correct order of the rate of alkaline hydrolysis of these esters?
$C H_{3} COOC H_{3} [r a t e = r_{1}]$ , $C H_{3} COO C_{2} H_{5} [r a t e = r_{2}]$ , $C H_{3} COO C_{3} H_{7} [r a t e = r_{3}]$

$r_{1} > r_{2} > r_{3}$

$r_{1} < r_{2} < r_{3}$

$r_{1} < r_{2} > r_{3}$

$r_{1} > r_{2} < r_{3}$

$r_{1} > r_{2} > r_{3}$ ,
Rate of hydrolysis decreases with increase in size of alkyl group
