Question

How many $S-S$ bonds, $S-O-S$ bonds, $\sigma$-bonds, and $\pi$-bonds are present in a trimer of sulphur trioxide?

• A. 0, 3, 16, 2
• B. 0, 3, 12, 6
• C. 0, 6, 12, 16
• D. 0, 4, 12, 6

Answer 1

Answer: (B)

0, 3, 12, 6

The option marked is incorrect. The correct option is B.

Here,

$S-S$ bond = 0

$S-O-S$ bond = 3

$\sigma$ = 3 + 9 = 12

$\pi$ bond = 6

Therefore the correct option is B.
