Explanation Draw the possible product for the given reaction is, The given 3 - b r o m o - 2 , 4 - d i m e t h y l p e n tan e has two identical β-positions. In an elimination reaction a proton and a halo group are eliminated. In the given elimination reaction, one β -proton and the bromine are eliminated. Since there are two β -protons, two alkene compounds are formed. Regiochemical approach for the given reaction: There are two β positions identical, the α , β position indicated below,

Question

Chapter 7, Problem 59PP

Interpretation Introduction

Interpretation:

The product has to be drawn and the reason for only one regiochemical outcome of the given reaction has to be explained.

Concept Introduction:

Elimination Reaction: It is just reverse reaction of addition where substituent from the given molecule is removed via E1 (the reaction depends only on the substrate involved in the reaction) or E2 (the reaction depends on both of the substituents in the reaction) mechanism.

Regiochemical reaction: Alkenes are formed when alkyl halides are treated with bases via β-elimination reaction. In β-elimination reaction, elimination of one proton and one halo group is taking place.

The product of the elimination reaction is depends upon the two β-elimination of alkyl halide. If the β-positions are identical and the products formed are also identical. If the β-positions are different and the products formed are also different. This means the double bond can form in two different regions so this type of reaction is called regio-selective and the products are called as regiochemical outcomes.
