Among $1$-butanol, $2$-butanol and $tert$-butanol, the order of reactivity in the Lucas test is
A3° > 2° > 1°
BAll equal
C1° > 2° > 3°
D2° > 3° > 1°
Answer & Solution
Correct answer: A. 3° > 2° > 1°
Lucas test forms a carbocation intermediate. Stability is 3° > 2° > 1° → reactivity follows the same order. $tert$-butanol is cloudy immediately; 1-butanol won't react at room temperature.
