Which of the following are true statements for the given compound in aqueous solution ?

Question

a) NH3 : A Bronsted base, but not a Lewis base

b) OH - : A Bronsted base and a Lewis base

c) CH3COOH : A Lewis acid, but not a Bronsted acid

d) Cu 2+(aq) : A Bronsted acid, but not a Lewis acid

e) C6H6 : Both a Bronsted acid and a Lewis acid

Answer 1

b is definitely true.
e doesn't dissolve in water, so it can't be true - and it doesn't donate protons, either.

That's all!
