Select incorrect statements(s):a)Electron-withdrawing inductive effect...
For the parent alkane, drop the terminal “e” and add the suffix “-oic acid”.The parent alkane is the longest continuous chain that contains the carboxylic acidfunctionality. The carbonyl carbon of the carboxylic acid receives the lowest number, C1,but this does not need to be specified. Recall that for carbons bearing oxygen, the higheroxidation state takes precedence. Therefore carboxylic acids > aldehydes > ketones >alcohols.

Select incorrect statements(s):a)Electron-withdrawing inductive effect...
Explanation:
The correct statement is option A.
Explanation of each option:
a) Electron-withdrawing inductive effect of the carbonyl group in the -COOH group weakens the O-H bond and favors ionization of a carboxylic acid compared with an alcohol.
- The carbonyl group in the -COOH group is electron-withdrawing in nature, meaning it withdraws electron density from the oxygen atom of the O-H bond.
- This weakens the O-H bond, making it easier to break and favoring the ionization of a carboxylic acid.
- Therefore, option A is correct.
b) Inductive effect of chlorine destabilizes the acid and stabilizes the conjugate base.
- The inductive effect of chlorine is electron-withdrawing in nature.
- This destabilizes the acid, as it withdraws electron density from the conjugate base, making it less stable.
- Therefore, option B is correct.
c) Aniline is a weaker base than ammonia.
- Aniline is a weaker base than ammonia due to the presence of the electron-donating aromatic ring.
- The presence of the aromatic ring in aniline decreases the availability of the lone pair of electrons on the nitrogen atom for donation, making it a weaker base compared to ammonia.
- Therefore, option C is correct.
d) Phenol is a weaker acid than water.
- Phenol is a weaker acid than water due to the resonance stabilization of the phenoxide ion formed after deprotonation.
- The resonance structures of the phenoxide ion distribute the negative charge over the oxygen atom and the aromatic ring, stabilizing the conjugate base.
- Therefore, option D is correct.
Conclusion:
The incorrect statement is option A. The electron-withdrawing inductive effect of the carbonyl group in the -COOH group weakens the O-H bond and favors ionization of a carboxylic acid compared with an alcohol.
