Reaction between acetone and methylmagnesium chloride followed by hydrolysis will give :
- Sec. butyl alcohol
- Tert. butyl alcohol
- Isobutyl alcohol
- Isopropyl alcohol
Answer
(2) Tert. butyl alcohol
Solution
As per NCERT, a ketone with a Grignard reagent followed by hydrolysis gives a tertiary alcohol.
(CH3)2C=O + CH3MgCl (CH3)3C-OMgCl
(CH3)3C-OMgCl H2O (CH3)3C-OH + Mg(OH)Cl
the product is 2-methylpropan-2-ol, i.e. tert-butyl alcohol.
