Question

Tert Butyl alcohol can be obtained by treating with CH3MgBr followed by hydrolysis
(a) HCHO
(b) CH3CHO
(c) CH3COCH3
(d) CH3CH2CHO

Answer 1

Answer:

Tert Butyl alcohol can be obtained by treating with CH3MgBr followed by hydrolysis:-CH3CHO

Answer 2

Tert Butyl alcohol can be obtained by treating with methyl magnesium bromide followed by hydrolysis with acetone.

• In this reaction, the Grignard reagent that is methyl magnesium bromide attacks the carbonyl carbon atom of acetone which is electrophilic and the methyl group get attached to the C atom and the MgBr group gets attached to the Oxygen atom.
• In the next step by hydrolysis, OMgBr is converted to OH and produces tert butyl alcohol.
• $CH_3COCH_3+CH_3MgBr\rightarrow (CH_3)_3COH$
• Thus, the correct option is c.
