Question

In the given, Lewis structure of $S_2{O}_3^{-2}$, formal change present on sulphur atoms $1$ and $2$ respectively are:

• A. zero, +1
• B. +1,+1
• C. +2,+2
• D. zero, zero

Answer 1

The correct option is A zero, +1

Lewis structure of $S_2{O}_3^{-2}$

Formal charge $=$ no. of valence electrons $-$ [non bonded electrons $+$ number of bonds]

$\to$ If a some atom is attached to other some atom then its formal charge is zero.

Ans ;- Option A.
