Question
The bond angle of the bond $C−O−C$ in methoxy methane is:
✓
Answer
Ethers feature $C–O–C$ linkage defined by a bond angle of about $110^\circ$ and $C–O$ bond length of about $140\ pm.$
In methoxymethane, the bond angle is $111.7^\circ $. Methoxymethane show positive deviation in the bond angle. This is basically due to the steric crowding on carbon atoms of methyl group.
Due to the crowding, the repulsion between bond pair of carbons and lone pair of oxygen is low. Thus, the bond angle of methoxymethane is $111.7^\circ.$
