Question

In alkaline hydrolysis of a tertiary halide by aqueous alkali, if concentration of alkali is doubled, then the reaction rate
A. will be doubled.
B. will be halved
C. will become four times greater
D. will remain constant.

Answer 1

Correct Answer - D
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.
