Understanding the Statements
The question presents two statements regarding the acidity of H2S and H2O.
Statement I: Electronegativity and Acidity
- Oxygen is indeed more electronegative than sulfur, which generally suggests that compounds with oxygen (like H2O) should exhibit stronger hydrogen bonding and stability.
- Despite this, H2S is considered more acidic than H2O. This can be attributed to the weaker H-S bond compared to the H-O bond, leading to easier release of H+ ions in H2S.
Statement II: Bond Strength Comparison
- The H-S bond in H2S is weaker than the H-O bond in H2O.
- A weaker bond means that less energy is required to break the bond, facilitating the release of protons (H+ ions) and thus contributing to the acidity of H2S.
Conclusion: Relationship Between Statements
- Both statements are correct:
- Statement I correctly identifies the relationship between electronegativity and acidity.
- Statement II provides a valid explanation for the acidity of H2S in comparison to H2O.
- Since Statement II effectively explains why H2S is acidic despite the higher electronegativity of oxygen, it supports Statement I.
Final Answer
Thus, the correct option is:
- a) Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I.
