Group showing strongest +M effect:
  • A
    −NH2​
  • B
    −N(CH3​)2​
  • C
    −NHCH3​
  • D
    −O-
✓

Answer

  1. −O-

Explanation:

(-) charge is a stronger donor than lone pairs hence the strongest +M effect is shown by −O-.

Also, the other species does not contain any negative charge thus option D is correct.
