Question

Which one of the following is correct statement regarding $E2$ reaction?

• A. Polar aprotic solvent favour $E2$ reaction
• B. Strong bases are preferred
• C. Rate depends on R-X and base used
• D. All of the above.

Answer 1

The correct option is D All of the above.

Polar aprotic solvent favours $E2$ reaction because in polar aprotic solvent, the base remains unsolvated and it readily attacks the proton.

A strong Base favours E2 reaction as it readily attacks the proton.

The rate of the reaction depends on the concentration of both the molecules involved.
$\text{Rate of the reaction}\propto [R-X{]}^1[Base{]}^1$
Hence correct option is d.
