Sulphur reacts with chlorine in 1:2 ration and forms X . Hydrolysis of X gives a sulphur compound Y. what is the structure and hybridisation of anion of Y

Options

A. Tetrahedral, `sp^3`
B. Linear, sp
C. Pyramidal, `sp^3`
D. Trigonal planar, `sp^2`

Answer

C

Explanation

When sulphur reacts with chlorine in 1 : 2 ratio, then `SCl_4` is obtained which on hydrolysis gives sulphurous acid `(H_2SO_3)`
`underset1S + underset2(2Cl_2) to underset((X))(SCl_4)`
`SCl_4 + 4H_2O to S(OH)_4 + 4HCl`
`S(OH)_4 to underset((Y))underset("sulphurous acid")(H_2SO_3) + H_2O`
The anion of (Y) is `SO_3^(2-)`
