For the Daniell cell Zn| Zn^(2+) || Cu^...

For the Daniell cell ` Zn| Zn^(2+) || Cu^(2+) | Cu` with The questions consist of two statements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following four responses :
The `pKa` of acetic acid is lower than that of phenol.
Phenoxide ion is more resonance stabilized.

A

If both assertion and reason are terue and the reason is the correct explanation of the assertion .

B

If both assertion ans reason are true but reason is not the correct explanation of the assertion .

C

If assertion is true but reason is false .

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
C
Lower the value of `pKa`, more acidic will be the compound . Acetic acid is more acidic than phenol. This ind should be more stable than the phenoxide ion and it is clear that carboxylate ion has more equivalen resonating stuctures than the phenoxide ion.
