Question

Statement 1: Ethers have low dipole moment and sp³ hybridised oxygen atom Statement 2: Ethers behave as Lewis base

• A. Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1
• B. Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1
• C. Statement 1 is True, Statement 2 is False
• D. Statement 1 is False, Statement 2 is True

Answer 1

Answer: (B)

Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1

Answer 2

Statement 1 is true because the oxygen in ethers is sp³ hybridized, resulting in a bent structure and two lone pairs. This structure, along with bond polarities, gives ethers a net but relatively low dipole moment compared to other polar molecules like alcohols.

Statement 2 is true because the oxygen atom in ethers has two lone pairs of electrons, which it can donate to Lewis acids, thus acting as a Lewis base.

Statement 2 does not explain Statement 1; they are both correct but distinct facts about ethers.
