Question

In which type of reaction a new π bond is added between two carbon atoms?
(A) Substitution
(B) Addition
(C) Elimination
(D) Rearrangement

Answer 1

Answer:Elimination

Explanation:

Answer 2

A new π bond is added between two carbon atoms in an (C) Elimination reaction.

Elimination reactions involve elimination of the various groups attached to carbon atoms in a hydrocarbon or organic compound, due to a series of steps. Such reaction typically involves the formation of a new π bond, since the empty valencies of the carbon atoms have to be filled up. Generally, the carbon atoms that undergo elimination need to be neighbouring atoms, and must be arranged in a certain manner for elimination to occur.
