Acetone on treatment with CH 3 − Mg − I and on further hydrolysis gives

Options

  1. AIsopropyl alcohol
  2. BPrimary alcohol
  3. CAcetic acid
  4. D2-methyl 2-propanol

Correct answer

D. 2-methyl 2-propanol

Step-by-step solution

Acetone reacts with Grignard's reagent to give tertiary alcohol. (CH 3 ) 2 C = O + CH 3 MgBr → H 2 O (CH 3 ) 3 C − OH tert-butyl alcohol
