Question

How many of the following compounds have $(pπ - dπ)$ multiple bonds?
$(i) {SO}_{2} (ii) {SO}_{3} (iii) H {SO}_{4}^{⊝} (iv) {SO}_{4}^{2 -} (v) {SO}_{3}^{2 -} (vi) H {SO}_{3}^{⊝}$

Moderate

Solution

${i. SO}_{2} \Rightarrow one (pπ - pπ) and one (pπ - dπ) bond.$
$ii. {SO}_{3} \Rightarrow one (p π - p π) and two (p π - d π) bond.$
$iii. {HSO}_{4}^{-} {and iv. SO}_{4}^{- 2} both have 2 (pπ - dπ) bond.$
$v. {SO}_{3}^{- 2} and vi . {HSO}_{3}^{⊝} both have one (pπ - pπ) bond.$
Thus, (i) to iv have $(pπ - dπ)$ multiple bonds.

How many of the following compounds have (pπ−dπ) multiple bonds?(i) SO2 (ii) SO3 (iii) H SO4⊝ (iv) SO42- (v) SO32- (vi) H SO3⊝

i. SO 2⇒ one (pπ−pπ) and one (pπ−dπ) bond. ii. SO3⇒ one (pπ−pπ) and two (pπ−dπ) bond. iii. HSO4- and iv. SO4-2 both have 2(pπ−dπ) bond. v. SO3-2 and vi.HSO3⊝ both have one (pπ−pπ) bond. Thus, (i) to iv have (pπ−dπ) multiple bonds.
