Major and minor product should be drawn for the given substrates during E2 elimination reaction. Concept Introduction: Elimination reaction: In elimination reaction, two substituents are removed from the substrate to give the product in presence of base. Elimination reactions are two types, E1 and E2. E1 reaction: elimination follows stepwise mechanism. E2 reaction: elimination follows concerted pathway of mechanism. Elimination of compound in presence of bulky base leads to less substituted alkene , in presence of strong base (not bulky) leads to more substituted alkene.

Interpretation Introduction

Interpretation:

Major and minor product should be drawn for the given substrates during E2 elimination reaction.

Concept Introduction:

Elimination reaction: In elimination reaction, two substituents are removed from the substrate to give the product in presence of base. Elimination reactions are two types, E1 and E2.

E1 reaction: elimination follows stepwise mechanism.

E2 reaction: elimination follows concerted pathway of mechanism.

Elimination of compound in presence of bulky base leads to less substituted alkene, in presence of strong base (not bulky) leads to more substituted alkene.
