Account for the following :
(a) Phosphorus shows high tendency for catenation.
(b) is more reactive than but is more reactive than .
(c) Nitrogen is found in gaseous state.
(d) Decomposition of ozone molecule is a spontaneous process.
(e) is inert towards hydrolysis.

(a) The bond strength of P-P is more tan N-N, therefore, phosphorus shows more tendency for catenation than nitrogen.
(b) Because the bond between Cl-F is weaker than the bond between Cl-Cl due to less effective overlapping of orbitals of Cl-F than Cl-Cl.
The is most reactive due to its high electrode potential.
(c) Due to small size and high electronegativity nitrogen forms multiple bonds, which are held together by weak Van-der Waal's forces of attraction which can be easily broken. Hence exists as a gas at room temperature.
(d) Because is thermodynamically unstable and its decomposition results in liberation of heat ( is -ve) and increase in entropy so becomes -ve and process becomes spontaneous.
(e) In S is protected by 6F atoms and does not allow molecules to attach on it. So inerts towards hydrolysis.
