In both water and diethyl ether, the central atom viz. O-atom has same hybridization. The why do they have different bond angles ? Which one has greater bond angle?

[prasanna]

Both water and diethyl ether have the central atom O in s {{p}^{3}} hybrid state with two lone pairs of electrons on O.

But due to the greater repulsions between two ethyl groups in diethyl ether than between two H-atoms in water result in greater bond angle (110°) in diethyl ether than 104.5° in that of water .
