Question

Sulphur reacts with chloric in 1 : 2 ratio and forms X. Hydrolysis of X gives a sulphurcompound Y. What is the structure and hydridisation of anion of Y?

Options

A.tetrahedral, sp3
B.linear,sp
C.pyramidal, sp3
D.trigonal planar, sp3

Solution

S + 2 Cl2 → SCl4
SCl2 + 4H2O → S(OH)4 + 4HCl
S(OH)4 → H2SO3 + H2O
The anion of y is SO32- in which S is sp3 hybridised with one lone pair of electrons on S, giving SO32- pyramidal shape.
