Question

Arrange the following groups in the order of decreasing (+I) effect.

(a) C6H5O^– > COO^– > CR3 > CHR2 > H

(b) C6H5O^– > H > CR3 > CHR2 > COO^–

(c) CR3 > C6H5O^– > H > COO^– > CHR2

(d) C6H5O^– > COO^– > CHR2 > CR3 > H

The question was posed to me during a job interview.

Answer 1

Correct answer is (a) C6H5O^– > COO^– > CR3 > CHR2 > H

For explanation I would say: The correct order is- C6H5O^– > COO^– > CR3 > CHR2 > H.
