In the following sequence of reaction identify the compound [C]:

Answer & explanation
Correct answer: option 4
The correct answer is option 4. 2-Methylpropan-2-ol.
The reaction will be as follows:

At first propan-2-amine reacts with \(HNO_2\) at \(0^oC\)followed by reaction with water to give compound [A] which is propan-2-ol.

After the formation of [A] the compound [A] undergoes oxidation let us say with PCC to give [B] which is Propan-2-one

After the formation of [B] the compound [B] reacts with methyl magnesium bromide followed by acid hydrolysis to give [C], i.e., 2-Methyl propan-2-ol
