The correct Answer is:
To solve the question regarding the assertion and reason about the bond angles in ethers and water, we can break it down into clear steps: ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that the C–O–C bond angle in ethers is higher than the H–O–H bond angle in water. - In ethers, the general structure is R–O–R', where R and R' are alkyl groups. In water, the structure is H–O–H. 2. **Analyzing the Bond Angles**: - The bond angle in water (H–O–H) is approximately 104.5 degrees. This is due to the two lone pairs of electrons on the oxygen atom, which repel the hydrogen atoms and compress the bond angle. - In ethers, the C–O–C bond angle is typically around 110 degrees or more. The presence of carbon atoms (R and R') creates a different steric environment compared to the hydrogen atoms in water. 3. **Hybridization Consideration**: - The reason states that oxygen in both ethers and water is sp hybridized. - However, this is incorrect. In both ethers and water, the oxygen atom is actually sp³ hybridized because it forms two sigma bonds (in water with hydrogen and in ethers with carbon) and has two lone pairs of electrons. 4. **Conclusion on Assertion and Reason**: - The assertion is true: the C–O–C bond angle in ethers is indeed higher than the H–O–H bond angle in water. - The reason is false: oxygen in both ethers and water is sp³ hybridized, not sp hybridized. - Therefore, the correct option is that the assertion is correct, but the reason is incorrect. ### Final Answer: - Assertion: True - Reason: False - Therefore, the correct option is C: A is correct, R is incorrect. ---
