Statement (A) Among the oxides of nitrogen, NO and `NO_(2)` are paramagnetic .
Statement (B) NO is paramagnetic in the gaseous state and diamagnetic in liquid state. The correct answer is

Options

A. (A) is correct (B) is not correct
B. Both (A) and (B) are not correct
C. (A) is not correct, (B) is correct
D. Both (A) and (B) are correct

Answer

D

Explanation

Statement (A) Among the oxides of nitrogen , NO and ` NO_(2)` are paramagnetic is the correct statement as N-atom contains unpaired electrons in its structure .
Structure of NO `to : overset(*)N = underset(* *)overset(* *) (O)` Structure of ` NO_(2) to (##ARH_5Y_SP_06_05_19_01_E03_029_S01.png" width="80%">
Statement (B) NO is paramagnetic in gaseous state and diamagnetic in liquid -state is also the correct statement as No in liquid state exists as dimer with no unpaired electron in the structune .

Hence, option (d) is the correct answer .
