Chapter 7, Problem 51PP

Interpretation Introduction

Interpretation:

The transition state for the given reaction should be draw and identified.

Concept Introduction:

Transition State: The state which defines the highest potential energy with respect to reaction co-ordinate between reactant and product. It is usually denoted by using the symbol ‘$\#$’.

Leaving group: it is a fragment that leaves substrate with a pair of electrons via heterolytic bond cleavage.

Nucleophile: donates pair of electrons to positively charged substrate resulting in the formation of chemical bond.

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.
