On hydrolysis, in aqueous acetone will give
(I)
(II)
(III)

A) Mixture of (i) and (ii)

B) Mixture of (i) and (iii)

C) Only (iii)

D) Only (i)

Correct Answer: A

Solution :

This is an example of \[{{\operatorname{S}}_{N}}1\] reaction involving carbocation as intermediate.

This carbocation is especially stabilised through resonance in which \[-\underset{\scriptscriptstyle\centerdot\centerdot}{\ddot{O}}-C{{H}_{3}}\]group acts as a good electron donor.

[A] \[\xrightarrow[\left( {{H}_{2}}O \right)]{aq.acetone}\]

[B] \[\xrightarrow[\left( {{H}_{2}}O \right)]{aq.acetone}\]
