Web23 jun. 2024 · 1. The HCH bond has 4 bonded pairs and 0 lone pairs, so the bond angle is 109.5 (tetrahedral). 2. The COH bond has 2 bonded pairs and 2 lone pairs (on the oxygen atom), so the bond angle is 104.5 (V-shaped or bent). Web14 jun. 2024 · For example in methanol C – O – H bond angle is 108.9°. In ethers, the C – O – C bond angle is slightly greater than tetrahedral angle. For example in dimethyl ether C – O – C bond angle is 111.7°. The larger bond angle in ethers may be because of greater repulsions between bulkier alkyl groups as compared to one H in alcohols.
