Question

The type of bonds present in sulphuric anhydride are

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

Answer 2

Sulphuric anhydride is $SO _{3}$ and its structure is as follows:

$\Rightarrow 3 \sigma, 1 p \pi-p \pi, 2 p \pi-d \pi$ bonds are present.
