NEETChemistryAlcohols Phenols and Ethers
Why is a tertiary halide formed when one of the alkyl groups in the ether is tertiary?
Options
- ATertiary groups are more reactive.
- BTertiary groups stabilise the carbocation intermediate.
- CTertiary groups prevent the formation of a carbocation.
- DTertiary groups enhance nucleophilic substitution.
Correct answer
B. Tertiary groups stabilise the carbocation intermediate.
Step-by-step solution
When one of the alkyl groups in the ether is tertiary, the resulting tertiary carbocation intermediate is more stable, leading to the formation of a tertiary halide.
