JEE Main Chemistry question

Increasing order of acid strength among tert-butanol, isopropanol, and ethanol is

(A)Ethanol < isopropanol < tert-butanol
(B)tert-Butanol < isopropanol < ethanolCorrect
(C)Isopropanol < tert-butanol < ethanol
(D)tert-Butanol < ethanol < isopropanol

Answer: (B)

Solution

More alkyl substitution at the carbinol carbon means more electron-donating (+I) groups destabilising the alkoxide conjugate base, so acidity decreases as branching increases; among these three,
