Question

i. $SO_{2}$ is produced by the action of hydrochloric acid on $Na_{2}SO_{3}$ .
ii. $SO_{2}$ is $sp^{2}$ hybridized.
iii. $SO_{2}$ has two $p\pi -p\pi $ bonds.
iv. $SO_{2}$ and $CS_{2}$ are isostructural.
How many of the above statements are correct?

Answer 1

Statements (i) and (ii) are correct. $SO_{2}$ has two $\pi $ bonds; one is $p\pi -p\pi $ and the other is $d\pi -p\pi $ .
$SO_{2}$ and $CS_{2}$ are isostrctural. $SO_{2}$ is bent while $CS_{2}$ is linear.
