State reasons for each of the following :
(i) All the P-Cl bonds in `PCl_5` molecule are not equivalent.
(ii) Sulphur has greater tendency for catenation than oxygen.

Sulphur has greater tendency for catenation than oxygen why?

State reasons for each of the following : (i) "The" N-O "bond in" NO_(2)^(-) "is shorter then the" N-O "bond in" NO_(3)^(-) . (ii) SF_(6) is kinetically an inert substance. OR State reasons for each of the following : (i) "All the" P-CI "bonds in" PCI_(5) "molecule are not equivalent". (ii) Sulpher has greater tendency for catenation then oxygen.

Why does sulphur have greater tendency for catenation than oxygen ?

Give reasons: Sulphur shows greater tendency for catenation than oxygen.
