Question

Consider the following statements with respect to the of oxides of sulphur:
(1) In gas phase, the $S{O}_2$ molecules are V shaped.
(2) In gas phase, the $S{O}_3$ molecules have a planar structure.
(3) $\gamma -S{O}_3$ exists as cyclic trimer in solid state at $273K$.
The correct statements are

• A. (1) and (2) only
• B. (2) and (3) only
• C. (1) and (3) only
• D. (1), (2) and (3)

Answer 1

The correct option is D (1), (2) and (3)

In gas phase, the $S{O}_2$ molecule undergoes $s{p}^2$ hybridization due to the presence of one lone pair and two bonding domains. This results in a V shaped geometry.
In the gas phase, $S{O}_3$ molecule undergoes $s{p}^2$ hybridization due to the presence of zero lone pair and three bonding domains. This results in a planar geometry.
$\gamma -S{O}_3$ exists as cyclic trimer in solid state at $273K.$
Thus, all the three statements are correct.
