Phenol is a weaker acid than acetic acid because
Options
- APhenoxide ion is better stabilized by resonance than acetate ion
- BAcetate ion is better stabilized by resonance than phenoxide ion
- CPhenol is led soluble in water than acetic acid
- DBoth phenoxide ion and acetate ion are stable
Correct answer
B. Acetate ion is better stabilized by resonance than phenoxide ion
Step-by-step solution
The negative charge in carboxylate ion is more dispersed in comparison to phenate (or phenoxide) ion, since there are two electronegative oxygen atoms in carboxylate ion as compared to one oxygen atom in phenoxide ion. -ve charge dispersed on -C carbon atoms.
