Question

The conversion of 2-methylpropan-1-ol to 2-methylpropan-2-ol is ______.

विकल्प

• addition reaction

• rearrangement reaction

• substitution reaction

• elimination reaction

Answer 1

The conversion of 2-methylpropan-1-ol to 2-methylpropan-2-ol is rearrangement reaction.

Explanation:

A rearrangement reaction occurs when 2-methylpropan-1-ol is converted to 2-methylpropan-2-ol. The carbon skeleton of a molecule is rearranged in these processes to produce a structural isomer of the original molecule. To make 2-methylpropan-2- ol, the alcohol group of 2-methylpropan-1-ol transfers from one atom to another inside the same molecule.
