Q.
Which statement is not correct about $NO _2$ ?
Chemical Bonding and Molecular Structure
Solution:
paramagnetic
Thus, (a) is correct
$2 NO _2 \rightleftharpoons N _2 O _4$
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
