How tert-butyl bromide reacts with aqueous KOH ? Give the mechanism and kinetics of · reaction.

Explanation

`underset(" Benzylbromide(A benzyl halides) ")(C_6 H_5 CH_2 Br) + KOH (aq) to underset("Benzylalcahol ")(C_6 H_5 CH_2 OH )+ KBr`
Mechanism of the reaction : The reaction. follows `S_(N^2)` ion mecharism because benzyl carbon is stable due to resonance.
` KOH (aq) to K^(+) (aq) + OH^(-)(aq)`
` C_6 H_5 CH_2 Br overset("slow")to C_6 H_5 CH_(2)^(+) +Br^(-)`
`C_6 H_5 CH_(2)^(+) +OH^(-) overset("Fast")to C_6 H_5 CH_2OH `
Kinetics of the reaction : Rate of reaction `= k[C_6H_5CH_2Br]`
