Reactivity of nucleophilic addition reaction depends upon carboniumion
. On increasing stability, reactivity decreases. Hence, decreasing order of reactivity is:

+ I

effect of

C H_{3}

group decreases reactivity of

Q. Increasing reactivity order of nucleophilic addition reaction of $H - ∣∣ O C - H; C H_{3} - ∣∣ O C - H$ and $C H_{3} - ∣∣ O C - C H_{3}$ will be

$H C H O > C H_{3} C H O > C H_{3} COC H_{3}$

$C H_{3} C H O > H C H O > C H_{3} COC H_{3}$

$C H_{3} COC H_{3} > C H_{3} C H O > H C H O$

$C H_{3} C H O > C H_{3} COC H_{3} > H C H O$
