JEE Mains · Chemistry · STD 12 - 6. Haloalkanes and Haloarenes
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.
- B Alkene will be the main product
- C Simple ether will form instead of mixed ether.
- D Expected mixed ether will be formed.
Answer & Solution
Correct Answer
(B) Alkene will be the main product
Step-by-step Solution
Detailed explanation
The tertiary alkylhalide undergo elimination reaction to give alkenes \(\begin{array}{*{20}{c}} {\,\,\,\,\,\begin{array}{*{20}{c}} {\,\,\,\,C{H_3}\,\,} \\ {|\,\,\,\,} \end{array}} \\ {C{H_3} - C - X + } \\ {\,\,\,\,\,|\,\,\,\,} \\ {\,\,\,\,\,\,\,\,\,C{H_3}\,\,\,} \end{array}\)…
