The 'Brown Ring Test' is an identification and conformation test of the nitrate ion  (NO₃^- ) using conc. H₂SO₄ and newly produced FeSO₄. Place the NO₃^-  containing sample in a test tube. Then, with gentle shaking, add conc H₂SO₄ dropwise, heat it briefly on a Bunsen burner, and add freshly made greenish FeSO4 Then, due to the creation of brown coloured  [Fe (H₂O)₅ (NO)]SO₄ complex, a brown ring forms in that test tube.

Correct option is (ii)

The valence electrons of nitrogen are two 2s and three 2p. Nitrogen can make three covalent bonds by sharing its three 2p electrons. Consider the NH₃ molecule. The nitrogen atom, however, still contains a lone pair of electrons in the 2s orbital. It can take one bond by transferring these two electrons from the lone pair. Consider the NH₄⁺ molecule.

As a result, nitrogen can create four different bonds.
