Account for the following:
(i) Sulphur in vapour form exhibits paramagnetic behaviour.
(ii) is more covalent than
(iii) is a stronger reducing agent than
(i) In vapour state sulphur partly exists as molecule which has two unpaired electrons in the antibonding II orbitals and hence exhibits paramagnetism.
(ii) in has more polarising power than
(iii) contains two P-H bonds while contains only one P-H bond therefore is stronger reducing agent.
