Question

phenol meta methoxyphenol pera methoxyphenol ortho methoxy phenol acidic strength

Answer 1

Answer:

Phenol is more acidic than Methoxy phenol. aromatic rings can exert and inductive effect as well as the resonance effect. When in the ortho,para-positions (relative to the -OH group of phenol), resonance tends to dominate while in the meta-position, the inductive effect is the only effect .

Explanation:

Phenol is more acidic than Methoxy phenol.

This is because:-

aromatic rings can exert and inductive effect as well as the resonance effect. When in the ortho,para-positions (relative to the -OH group of phenol), resonance tends to dominate while in the meta-position, the inductive effect is the only effect . For the methoxy group, the oxygen bonded to the ring is more electro negative than carbon so it will increase acidity of the phenol -OH group. In the para-position (4-methoxy phenol), only resonance will be at play and because it donates electron by resonance, this will decrease acidity. The ortho-position (2-methoxy phenol) is a little unique. The resonance effect is identical with the para-position (decrease in the acidity) but the inductive effect is quite strong and may override the resonance effect.
