Though ethers are the derivatives of water, the two differ in bond angles. Explain

Text Solution

Verified by Experts

In bond the moleculesk the oxygen atom is `sp^(3)` hybridised and the expected bond `109^(@)28'`
However, the presence of two lone pairs distorts the geometry of both these molecules. the bond angle in dienthyl ether molecule is more than in case of water molecule because of greater repulsion in two `C_(2)H_(5)` group as compared to H atoms in the molecule of water.
