Question

In which of the following species $S-$atom assumes $s{p}^3$-hybrid state?
(I) $S{O}_3$
(II) $H_{2}S$
(III) $S{O}_2$
(IV) $S_8$

• A. (I) and (II)
• B. (II) and (III)
• C. (II) and (IV)
• D. (III) and (IV)

Answer 1

Answer: (C)

(II) and (IV)

$\left(i\right){SO}_3\to {sp}^2\left(ii\right)H_{2}S\to {sp}^3\left(iii\right){SO}_2\to {sp}^2\left(iv\right)S_8\to {sp}^3$

Only $H_{2}S$ and $S_8$ have ${sp}^3$ hybridised $S-atom$. So $\left(ii\right)$ and $\left(iv\right)$ are correct.
