Question:
In both water and dimethyl ether (CH3 —Ο — CH3 ), the oxygen atom is the central atom and has the same hybridization, yet they have different bond angles. Which one has a greater bond angle? Give reason.
Solution:
Dimethyl ether will have a greater bond angle. There will be more repulsion between bond pairs of CH3 groups attached in ether than between bond pairs of hydrogen
atoms attached to oxygen in the water.
