WebJan 25, 2024 · Hence acetate ion is more stable than phenoxide ion. Thus acetic acid is more acidic. Acetic acid - 4.76 Phenol-10.02 Thus, we can say that Pka phenol > Pka acetic acid OR ka phenol < ka acetic acid i.e. The acid dissociation constant for acetic acid is much than phenol. i.e.The amount of H+ released by Acetic acid is more than phenol. WebPhenol (systematically named Benzenol, also called carbolic acid or phenolic acid) is an aromatic organic compound with the molecular formula C 6 H 5 OH.It is a white crystalline solid that is volatile.The molecule …
