Question

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

• A. Primary > Secondary > Tertiary
• B. Primary < Secondary < Tertiary
• C. Primary < Secondary > Tertiary
• D. Primary > Secondary < Tertiary

Answer 1

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.
