Which of the following statements is wrong?
AnswerClick to flip back
A
Single N-N bond is stronger than the single P-P bond.
💡 Explanation:
N-N sigma bond (single bod) is weaker than P-P sigma bond (single bond) due to the small bond length between the nitrogen atoms. The lone pair of electrons of both the atoms nitrogen repel each other making the single bon between $N-N$ weaker than P-P sigma bond.In $P-P$ bond the repulsion between sigma bond and lone pair electrons is less as the size of phosphorous is large.
So statement A is wrong.
Hence option A is correct.
