S + conc. `H_2SO_4 rightarrow X+Y` here X is a gas and Y is a liquid and both are triatomic molecules. The number of electron lone pairs present on the central atoms of X and Y are respectively.

Options

A. 2, 1
B. 1, 0
C. 1, 2
D. 2, 2

Answer

C

Explanation

When sulpher (S) react with the `H_(2)SO_(2)` (c0nc), the following reaction takes place
`S + 2H_(2) SO_(4) (conc) to 3SO_(2) + 2H_(2)O`
As `SO_(2)` has one lone pair of electrons over central atom (i.e., sulpher)
And `H_(2)O` has two lone pair of electrons over central atom (i.e., oxygen)
Hence (c) is the correct option
