MCQ
Compare relative stability of the following resonating structure.
  • ✓
    $(i) > (ii) > (iii)$
  • B
    $(ii) > (i) > (iii)$
  • C
    $(i) > (iii) > (ii)$
  • D
    $(ii) > (iii) > (i)$
✓

Answer

Correct option: A.
$(i) > (ii) > (iii)$
a
$(a)$ $(1)$ Neutral $R.S.$ are most stable.
$(2)$ With the increase in charge separation stability of $R.S.$ decreases. So  stability order is $I > II > III$
