In alkaline hydrolysis of a tertiary halide by aqueous alkali, if concentration of alkali is doubled, then the reaction rate

will be doubled.

will be halved

will become four times greater

will remain constant.

Text Solution

Verified by Experts

The correct Answer is:

In tertiary alkyl halides, the reaction rate depends upon the concentration of tertiary alkyl halide only sinice it proceeds by `S_(N^(1))` mechanism. Since the concentration of alkyl halide does not change, reaction rate remains unchanged.
