Which of the following alkyl halides undergoes hydrolysis with aqueous KOH at the fastest rate?

A) \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}Cl\]

B) \[C{{H}_{3}}C{{H}_{2}}Cl\]

C) \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}Cl\]

D) \[C{{H}_{3}}C{{H}_{2}}CH(Br)C{{H}_{3}}\]

Correct Answer: D

Solution :

 will undergo hydrolysis at the fastest rate because rate of reaction for hydrolysis of alkyl halidesis \[3{}^\circ >2{}^\circ >1{}^\circ .\]
