Question

The C−O−C angle in ether is about ______.

Options

• 180°

• 190°28'

• 110°

• 105°

Answer 1

The C−O−C angle in ether is about 110°.

Explanation:

Oxygen in ethers is effectively sp3-hybridised (two C–O bonds + two lone pairs), so the electron pairs adopt a roughly tetrahedral arrangement; lone‑pair–bond‑pair repulsion slightly alters the ideal angle, giving C–O–C values ≈ 110 – 112°.
