Which of the following compound would not react with Lucas reagent at room temperature?

Options

A. `H_(2)C=CHCH_(2)OH`
B. `C_(6)H_(5)CH_(2)OH`
C. `CH_(3)CH_(2)CH_(2)OH`
D. `(CH_(3))_(3)COH`

Answer

C

Explanation

The order of reactivity of alcohol towards Lucas reagent is `3^(@)gt2^(@)gt1^(@)`. Therefore, `1^(@)`-alcohol donot react with Lucas reagent at room temperature. The benzyl and allyl alcohols react as rapidly as `3^(@)` alcohols with Lucas reagent because their carbocations are resonance stabilised and are stable. Thus, `CH_(3)CH_(2)CH_(2)OH` (`1^(@)` alcohol) is least reactive.
