Question

Which of the following statement is wrong?(a) The stability of hydride increases from NH₃ to BiH₃ in group 15 of the periodic table.(b) Nitrogen cannot form dπ – pπ bond.(c) Single N – N bond is weaker than the single P – P bond.(d) N₂O₄ has two resonance structures.

Answer 1

Gonna answer in the comments:)

Answer 2

Answer:

here it is

Explanation:

N−N single bond is weaker than P−P bond due to smaller size of N as compared to P. Smaller size of N leads to smaller N−N bond length. As a result, the lone pair of electrons on the both the N atoms repel each other leading to unstability or weakening of N−N bond.
