Question

The order of reactivity of alcohols towards Na or K metal is:


A
Primary > Secondary > Tertiary
loader
B
Primary < Secondary < Tertiary
loader
C
Primary < Secondary > Tertiary
loader
D
Primary > Secondary < Tertiary
loader

Solution

The correct option is A Primary > Secondary > Tertiary
For the reactions of alcohols with sodium or potassium metal, the order of reactivity of alcohols is, 
Primary > Secondary > Tertiary.

Thus, primary alcohols have maximum reactivity and tertiary alcohols have minimum reactivity.

Because in tertiary alcohol the more alkyl number of alkyl groups decreases acidity.

Option A is correct.
