The strength of an acid depends on?
Correct answer: D. Depends on both ease of removal of proton and stability of the anion formed
- A. Ease of removal of proton
- B. Stability of the anion formed
- C. Stability of the cation formed
- D. Depends on both ease of removal of proton and stability of the anion formed
Explanation
The correct option is: Depends on both ease of removal of a proton and stability of the anion formed.Explanation:The strength of an acid is determined by its ability to donate a proton (H+) in a chemical reaction. This is often represented by the equation:Acid (AH) ⇌ H+ + Anion (A-)In this equation, the acid (AH) donates a proton (H+) to form the conjugate base or anion (A-). The strength of an acid is influenced by two main factors:Ease of removal of a proton: The more readily an acid can donate a proton, the stronger it is. Acids with weak bonds between hydrogen and the rest of the molecule are more likely to lose the proton and, thus, are stronger acids.Stability of the anion formed: After the acid donates its proton, the resulting anion (conjugate base) is formed. A stable anion is better able to handle the negative charge that results from gaining an electron. An unstable or highly reactive anion will make the acid weaker.Together, these factors play a crucial role in determining the strength of an acid. Acids with both a high tendency to release protons (ease of removal of a proton) and produce stable anions are considered strong acids. On the other hand, weak acids have a lower tendency to donate protons and/or form less stable anions.In summary, the strength of an acid depends on both the ease of removal of a proton and the stability of the anion formed after the proton donation.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
