a) CH3Br + NaOH → CH3OH + NaBr
Interpretation:
The reaction CH3Br + NaOH → CH3OH + NaBr is to be classified as an addition, elimination, substitution or rearrangement reaction.
Concept introduction:
In addition reactions two reactants add together to form a single product. In elimination reactions a single reactant splits in to two products often with the formation of small molecules like water, HBr etc. In substitution reactions two reactants exchange parts to give new products. In rearrangement reactions a single reactant undergoes a reorganization of bonds and groups to yield a new isomeric product.
To classify:
The reaction CH3Br + NaOH → CH3OH + NaBr as an addition, elimination, substitution or rearrangement reaction.
b) CH3CH2Br → CH2=CH2 + HBr
Interpretation:
The reaction CH3CH2Br → CH2=CH2 + HBr is to be classified as an addition, elimination, substitution or rearrangement reaction.
