Identify the species having one π\pi -bond and maximum number of canonical forms from the following :Identify the species having one π -bond and maximum number of canonical forms from the following :

Options

  1. ASO3{SO}_{3}
  2. BO2{O}_{2}
  3. CSO2{SO}_{2}
  4. DCO32−{CO}_{3}^{2 -}

Correct answer

D. CO32−{CO}_{3}^{2 -}

Step-by-step solution

Among SO3,O2,SO2{SO}_{3}, {O}_{2}, {SO}_{2} and CO32−{CO}_{3}^{2 -}, only O2{O}_{2} and
CO32−{CO}_{3}^{2 -} has only one π\pi -bond
