Aldehydes Ketones Question 103

Question: Identify the reactant X and the product Y $ CH_3-CO-CH_3+X\to \underset{{}}{\mathop{{{(CH_3)}_3}}}C-OMg-Cl $ $ Y+Mg\ (OH)\ Cl $

[Kerala PMT 2003]

Options:

A) $ X=MgCl_2;\ \ Y=CH_3CH=CH_2 $

B) $ X=CH_3MgCl;\ Y=C_2H_5COCH_3 $

C) $ X=CH_3MgCl;\ Y={{(CH_3)}_3}\ C-OH $

D) $ X=C_2H_5MgCl;Y={{(CH_3)}_3}C-OH $

Show Answer

Answer:

Correct Answer: C

Solution:

$ CH_3COCH_3+\underset{\text{(X)}}{\mathop{CH_3MgCl}}\to {{(CH_3)}_3}C-OMgCl $

$ \xrightarrow{hydrolysis}{{(CH_3)}_3}\underset{(Y)}{\mathop{C-OH}}+Mg(OH)Cl $
