Among the following compounds, the most acidic is: [JEE-2011]
a)
p - nitrophenol
b)
p - hydroxybenzoic acid
c)
o - hydroxybenzoic acid
d)
p - toluic acid
Correct answer is option 'C'.
Ortho-isomer, a strong hydrogen bridge can be formed between the phenolic -OH and the the carboxylate anion. This will tend to stabilize the conjugated carboxylate base, and hence will increase acidity.
this is the order of acidic
ortho hydroxy B.acid > meta hydroxy B.acid > benzoic acid > para hydroxy B. acids.
