Question

In both water and dimethyl ether , oxygen is central atom same hybridisation yet different bond angle. which one is grater bond angle give reason

Answer 1

Dimethyl ether will have a greater bond angle due to steric hindrance and repulsions of bulky methyl groups.

Answer 2

Answer:

Dimethyl ether

Explanation:

Hey

Dimethyl ether will have larger 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 water. The carbon of CH3 in ether is attached to three hydrogen atoms through σ bonds and electron pairs of these bonds add to the electronic charge density on carbon atom. Hence, repulsion between two —CH3 groups will be more than that between two hydrogen atoms.
