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

A)  tetrahedral, \[(-z-x+2y)kJ\]       

B)  linear, \[sp\]    

C)         pyramidal, \[(-x-2y-z)kJ\]  

D)        trigonal planar, \[(-x-2y+z)kJ\]

Correct Answer: C

Solution :

When sulphur reacts with chlorine in 1: 2 ratio, then \[BaC{{l}_{2}}\] is obtained which on hydrolysis gives sulphurous acid \[KCl\]. \[-{{2}^{o}}C\] \[BaC{{l}_{2}}\] \[-{{3}^{o}}C\] The anion of (V) is \[+{{3}^{o}}C\]
