Chapter 14.5, Problem 14.7P

Interpretation Introduction

Interpretation:

The reason for readily dehydration reaction shown by givenalcohol A compared to alcohol B should be explained.

Concept Introduction:

When H₂O is lost from a material it is known as dehydration. When an alcohol is treated with a strong acid such as H₂SO₄, a water molecule is lost by breaking two adjacent bonds C-OH and C-H and forming a new double bond, producing an alkene. This is an elimination reaction.

  

In this reaction, more than one type of alkene may produce. But one of them is the major product. The Zaitsev rule states that the major product in elimination is the alkene that has more alkyl groups bonded to it.
