Question

An ether which cannot be directly prepared by WiIliamson’s synthesis method is

Options:

CH3 – O – CH3

Ph – O – CH2 – Ph

(CH3)3C – O – C2H5


CH3 – CH = CH – O – CH = CH2

Answer 1

Answer:

An ether which cannot be directly prepared by WiIliamson’s synthesis method is  CH3 – CH = CH – O – CH = CH2

Answer 2

Answer:

An ether which cannot be directly prepared by WiIliamson’s synthesis method is ter-butyl bromide.

Explanation:

1. To make di-tert-butyl ether, tert-butyl bromide must be reacted with sodium tert-butoxide. 2)
2. Alkoxides are strong bases in addition to being nucleophiles. They react in three ways.
3. The elimination reaction is triggered by alkyl halides.
4. Elimination occurs when tert-butyl bromide combines with sodium tert-butoxide instead of substitution.
5. Instead of di tert butyl ether, isobutylene is generated as a result of this elimination process.
6. An ether which cannot be directly prepared by WiIliamson’s synthesis method is ter-butyl bromide.
