Which of the Following Statements is True: (a)Melting point of Phosphorous is Less Than that of Nitrogen (b)`N_{2}` is Highly Reactive While `P_{4}` is Inert | Bzziii

Which of the following statements is true: 

(a)Melting point of Phosphorous is less than that of Nitrogen 
(b)`N_{2}` is highly reactive while `P_{4}` is inert 
(c)Nitrogen shows higher tendency of catenation than P 
(d)N-N is weaker than P-P




(d)N-N is weaker than P-P

Explanation:

other statements as incorrect as Phosphorus has a higher melting point due to bigger size than Nitrogen. Nitrogen is inert due to formation of triple bonds and has a lower covalence due to non - availability of d – orbitals.
