Statement-I: Acidic strength of $\mathrm{R}–{\mathrm{CH}}_2\mathrm{OH}>{\mathrm{R}}_2\mathrm{CHOH}>{\mathrm{R}}_3\mathrm{COH}$

Statement-II: $\mathrm{O}–\mathrm{H}$ bond polarity in $\mathrm{R}–{\mathrm{CH}}_2\mathrm{OH}>{\mathrm{R}}_2\mathrm{CHOH}>{\mathrm{R}}_3\mathrm{COH}$

As the number of +I groups increase (alkyl groups increase), non-polar nature of alcohol increases, O-H bond polarity decreases.

(or)

Increase in the number of alkyl groups, (+I groups) decreases the electronegativity of oxygen atom, O-H bond polarity decreases.
