The correct order of reactivity of Phenylmagnesium Bromide (PhMgBr) with PhCOPh, CH₃CHO, CH₃COCH₃ is:

c) PhCOPh < CH₃COCH₃ < CH₃CHO

  • CH₃CHO is the most reactive in comparison to the other two because alkyl group has +I effect and hence greater the number of alkyl attached to the carbonyl group, its reactivity decreases
  • Also, as the steric crowding on the carbonyl group increases, the reactivity decreases accordingly.

The correct order of reactivity of Phenylmagnesium Bromide (PhMgBr) with PhCOPh, CH₃CHO, CH₃COCH₃ is:

(c) PhCOPh < CH₃COCH₃ < CH₃CHO

Explanation:

The correct order of reactivity of Phenylmagnesium Bromide (PhMgBr) with PhCOPh, CH₃CHO, CH₃COCH₃ is:

(c) PhCOPh < CH₃COCH₃ < CH₃CHO

It is because CH₃CHO is the most reactive in comparison to the other two compounds.

Greater the number of alkyl groups attached to the carbonyl group, its reactivity decreases as alkyl group has +I effect.
