Question

. Phenol is more acidic than cyclohexane why?​

Answer 1

Answer:

Phenol, for example is about 1,000,000 times stronger an acid than cyclohexanol because the conjugate base of phenol is much more stable than the conjugate base of cyclohexanol. ... That is, somehow the presence of these electronegative atoms must stabilize the conjugate base anion.

Answer 2

Answer:

Phenol is more acidic than cyclohexanol and acyclic alcohols because the phenoxide ion is more stable than the alkoxide ion. In an alkoxide ion, such as the one derived from cyclohexanol, the negative charge is localized at the oxygen atom.

Explanation:

Phenols are much more acidic than alcohols because the negative charge in the phenoxide ion is not localized on the oxygen atom as it is in an alkoxide ion but is delocalized as it is shared by a number of carbon atoms in benzene ring
