Question

CH3OH is a which type of Acid: 1 - Bronsted Acid 2- Lewis acid 3- Arrhenious Acid 4. Lewis acid and Arrhenious Acid​

Answer 1

Explanation:

Methanol is a lewis acid due to it also being a Bronsted-Lowry acid. That's because: Methanol can donate a proton, i.e. it is a Bronsted-Lowry acid

I hope it will help you bro

Answer 2

CH3OH is formerly known as Methanol, Methyl Alcohol, or Wood spirit. CH3OH is a volatile, colorless, inflammable light liquid with a distinct smell. CH3OH can as a Bronsted acid and Lewis acid both. And both options 'A' and 'B' are correct.

• Bronsted Acid is a type of acid that can donate protons or accepts electrons by having a vacant orbital. CH3OH accepts protons, So it is a Bronsted acid. So, option 'A' is correct.
• Lewis acid is a type of acid that donates lone pairs of electrons. CH3OH accepts protons by donating electrons. CH3OH is a Lewis acid. So, option 'B' is also correct.
• Arrhenius acid is a type of acid that is capable of donating hydrogen or hydronium ions. CH3OH donates OH- not H+. CH3OH is not an Arrhenius Acid. So, option 'C' is incorrect.
• Since CH3OH is a lewis acid but not an Arrhenius acid. So, option 'D' is also incorrect.

Hence, CH3OH can act as a Bronsted acid and Lewis acid both. And both options 'A' and 'B' are correct.
