Question

Which statement is not correct about $N{O}_2$ ?

• A. It is paramagnetic
• B. It forms dimer and paramagnetism is lost
• C. It has one coordinate bonds
• D. It has nitrogen oxygen triple bond

Answer 1

Answer: (D)

paramagnetic
Thus, (a) is correct
$2N{O}_2\rightleftharpoons N_2{O}_4$
In $N_2{O}_4$ formation, unpaired electron is used.
Thus, paramagnetism is lost
Thus, (b) is correct
It is one coordinate bond. Thus, (c) is correct
There is no triple bond. Thus (d) is incorrect
