Assertion. `t`-Butyl Methyl ether is not prepared by the reaction of `t-`butyl bromide with sodium methoxide.
Reason: Sodium methoxide is a strong nucleophile.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but reason is false

D

If both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
B

In Williamson's synthesis, if a tertiary alkyl halide is used, an alkene is the only reaction product and no ether is formed.
`CH_(3)-overset(CH_(3))overset(|)underset(CH_(3))underset(|)C-Br+NaOCH_(3)rarrCH_(3)-underset("2-methyl propene")underset(CH_(3))underset(|)C=CH_(2)+NaBr`
It is because alkoxides are not only nucleophiles but also strong bases as well. They react with alkyl halides leading to elimination reaction.
