Question

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

• A. addition reaction
• B. rearrangement reaction
• C. substitution reaction
• D. elimination reaction

Answer 1

Answer: (B)

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.
