Question
Which of the following statements is wrong?
A.
Single $$N-N$$ bond is stronger than the single $$P-P$$ bond.
B.
$$P{H_3}$$ can act as a ligand in the formation of coordination compound with transition elements.
C.
$$N{O_2}$$ is paramagnetic in nature.
D.
Covalency of nitrogen in $${N_2}{O_5}$$ is four.
Answer :
Single $$N-N$$ bond is stronger than the single $$P-P$$ bond.
Solution :
The single $$N-N$$ bond is weaker than the single $$P- P$$ bond because of high inter-electronic repulsions of the non-bonding electrons, owing to the small bond length.
