Why nitrogen shows catenation properties less than phosphorus?

Catenation power of nitrogen is less because N-N bond is weaker than the single P-P bond. N-N single bond is weaker than P-P bond is due to smaller size of nitrogen atom there is stronger inter electronic repulsion between nitrogen atoms hence it form strong pπ–pπ multiple bond and become diatomic molecule.

Which will have very fast tendency to dimerized ClO2 or NO and why?


In case of ClO2 odd electron is delocalized over 3 atoms so extent of delocalization of odd electron is higher in comparison to NO. Hence tendency of demerisation of a NO is faster that of ClO2.

Although electron affinity of chlorine is higher than fluorine, yet fluorine act as better oxidizing agent than chlorine? Explain.


Oxidizing character of elements calculated in aqueous medium while electron affinity is the term related to gaseous state.

Since fluorine possesses small size and high negative charge density thus undergoes more hydration as compared to chlorine as result of which its hydration energy increases than electron affinity and thus fluorine takes electron easily in aqueous medium and act as best oxidizing agent.The another reason of high oxidizing power of fluorine is its low bond dissociation energy as compare to chlorine.
