Question

Which is more acidic catechol or resorcinol?

Answer 1

i am nt sure abt d answer but it is catechol i guess

Answer 2

Answer:

hydroquinone<resorcinol<phenol<catechol

Explanation:

This question is from a book that gives the answer as

hydroquinone<resorcinol<phenol<catechol

but does not provide any explanation for the answer. If I go by the stability of the conjugate base due to resonance, phenol seems to have the most number of resonance intermediates and seems to be most stable. Considerations about number of resonance intermediates of conjugate base gives an order that is nowhere close to that provided as an answers.
