CH_(3)-overset(CH_(3))overset(|)(CH)-NO_(2) underset(at 0^(@)C)overset(NaNO_(2)+H_(2)SO_(4))(rarr)(A). (A) is:

Answer»

a.`(CH_(3))_(2)-CH-OH`
b.`(CH_(3))_(2)CH-N=N-Br`
c.`(CH_(3))_(2)underset(NO_(2))underset(|)(C)-N=O`
d.`(CH_(3))_(2)underset(NO_(2))underset(|)(C )-NHOH`

Solution :The `2^(@) (RNO_(2))` group reacts with `HNO_(2) (2NaNO_(2)+H_(2)SO_(4) rarr 2HNO_(2) + 2Na_(2)SO_(4))` to GIVE pseudonitrole, which gives blue colour with `NaOH`.

So the answer is `(c )`.
