Question
Chapter 8, Problem 6PP
Interpretation Introduction
Interpretation:
The mechanism for the formation of 2, 3-dimethyl-2-butanol from 3, 3-dimethyl-1-butene is to be written.
Concept introduction:
A reaction in which a water molecule is added to an unsaturated compound is called acid catalyzed hydration.
The order of stability of carbocation is such that tertiary carbocation is the most stable, primary carbocation is the least stable, and secondary carbocation lies between primary and tertiary carbocation.
