The conversion of 2- methylpropan – 1 – ol to 2- methylpropan -2- ol is

Step-by-step solution

The conversion of 2- methylpropan -1- ol to 2- methylpropan – 2 – ol is a rearrangement reaction. In these reactions, the carbon skeleton of a molecule is rearranged to give a structural isomer of the original molecule. Here, the alcohol group of 2 – methylpropan – 1 – ol moves from one atom to another atom in the same molecule to give 2 – methylpropan – 2 – ol.
