MCQ
The bond angle of the bond C−O−C in methoxy methane is:
- A111.7
- B109
- C108.9
- D180
✓
Answer
- 111.7
Explanation:
Ethers feature C–O–C linkage defined by a bond angle of about 110° and C–O bond length of about 140pm.
In methoxymethane, the bond angle is 111.7°. 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 111.70.
