Question

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

• A. will be doubled
• B. will be halved
• C. will remain constant
• D. None of the above

Answer 1

The correct option is C will remain constant

In alkaline hydrolysis of tertiary halide by aqueous alkali, if concentration of alkali is doubled, then the reaction will remain constant because t-alkyl halides with aqueous alkali give $S_{N}1$ reaction and the rate of $S_{N}1$ reaction is not based upon the concentration of nucleophile (i.e., alkali).
