R−OH+HX→R−X+H2OR - OH + HX \rightarrow R - X + H_{2}O

In the above reaction, the reactivity of different alcohols is.

A

Tertiary > Secondary > Primary

B

Tertiary < Secondary < Primary

C

Tertiary < Secondary > Primary

D

Secondary < Primary < Tertiary

Answer

Tertiary > Secondary > Primary

Explanation

Solution

R−OX+HX→R−X+H2OR - OX + HX \rightarrow R - X + H_{2}O

Reactivity order of alcohols for this reaction

3o>2o>1o3^{o} > 2^{o} > 1^{o}

Reactivity order of halogen acids

R−I>R−Br>R−ClR - I > R - Br > R - Cl
