Given below are two statements.
Statement I : Phenols are weakly acidic.
Statement II : Therefore they are freely soluble in solution and are weaker acids than alcohols and water.
Choose the most appropriate option
Options
- ABoth Statement I and Statement II are correct.
- BStatement I is correct but Statement II is incorrect.
- CStatement I is incorrect but Statement II is correct.
- DBoth Statement I and Statement II are incorrect.
Correct answer
B. Statement I is correct but Statement II is incorrect.
Step-by-step solution
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 delocalised as it is shared by a number of carbon atoms in the benzene ring.
Phenol are weakly acidic. Phenol is more acidic than alcohol & statement (I) is correct. (II) is incorrect.
