Question

The type of bonds, present in sulphuric anhydride are

• A. $3\sigma$ and $3p\pi -d\pi$
• B. $3\sigma ,1p\pi -p\pi$ and $2p\pi -d\pi$
• C. $2\sigma$ and $3p\pi -d\pi$
• D. $2\sigma$ and $2p\pi -d\pi$

Answer 1

Answer: (B)

$3\sigma ,1p\pi -p\pi$ and $2p\pi -d\pi$

Sulphuric anhydride is $S{O}_3$ and its structure is as follows,

$\Rightarrow 3\sigma$ - bond deciding the shape of the molecule, $1p\pi -p\pi$ and $2p\pi -d\pi$ bonds are present.
