(CH3)3CMgCl{{(C{{H}_{3}})}_{3}}CMgCl on reaction with D2O{{D}_{2}}O produces

A

(CH3)3COD{{(C{{H}_{3}})}_{3}}COD

B

(CD3)3CH{{(C{{D}_{3}})}_{3}}CH

C

(CH3)3CD{{(C{{H}_{3}})}_{3}}CD

D

(CD3)3CD{{(C{{D}_{3}})}_{3}}CD

Answer

(CH3)3CD{{(C{{H}_{3}})}_{3}}CD

Explanation

Solution

(CH3)3C−MgClGrignard reagent +D.OD→(CH3)3C.D\underset{Grignard\text{ }reagent}{\mathop{{{(C{{H}_{3}})}_{3}}C-MgCl}}\,+D.OD\xrightarrow{{}}{{(C{{H}_{3}})}_{3}}C.D +MgCl(OD)+MgCl(OD) [Grignard reagent when reacts with a protic solvent, gives alkane.]
