In Williamson synthesis of mixed ether having a primary and a tertiary alkyl group if tertiary halide is used, then :

• A

  Rate of reaction will be slow due to slow cleavage of carbon-halogen bond.
• Correct answer
  B

  Alkene will be the main product.
• C

  Simple ether will form instead of mixed ether.
• D

  Expected mixed ether will be formed.

Solution

The tertiary alkyl halide undergo elimination reaction to give alkenes

Hence, the correct answer is option: 'B'.
