Question

Which alcohol is the most acidic?

Answer 1

1. Alcohols are acidic due to the presence of polarity of $\mathrm{O}-\mathrm{H}$ bond.
2. The electron releasing group like ${\mathrm{CH}}_3,{\mathrm{C}}_2{\mathrm{H}}_5$ increases electron density on oxygen atoms which decreases the polarity of $\mathrm{O}-\mathrm{H}$ bond.
3. And thus acidic strength is also decreased.
4. The acidity order is thus Primary alcohol > Secondary Alcohol > Tertiary Alcohol.
5.
