Question
$$R - OH + HX \to RX + {H_2}O$$
In the above reaction, the reactivity of alcohols is
A.
tertiary > secondary > primary
B.
tertiary < secondary < primary
C.
tertiary > primary > secondary
D.
secondary > primary > tertiary
Answer :
tertiary > secondary > primary
Solution :
Reactions of alcohols involving cleavage of $$C - OH$$ bond follow the reactivity order :
Tertiary > secondary > primary, according to the stability of carbocation intermediate.
