Question

The type of bonds present in sulphuric anhydride are -

• A. $3 \sigma$ and three $p \pi - d \pi$
• B. $3 \sigma$ one $p \pi - p \pi$ and two $p \pi - d \pi$
• C. $2 \sigma$ and three $p \pi - d \pi$
• D. $2 \sigma$ and two $p \pi - d \pi$

Answer 1

Answer: (B)

$3 \sigma$ one $p \pi - p \pi$ and two $p \pi - d \pi$

Answer 2

The correct option is (B): 3σ, one pπ−pπ and two pπ−dπ
Sulphuric anhydride is $SO_3$ and its structure is as follows:
$\Rightarrow \, \, 3 \sigma , 1 \, p \pi , 2\, p \pi - d \pi$ or 1 pπ−pπ and 2pπ−dπ bonds are present.
