1.	Inboth water anddimathyl ether (CH_(3) - overset(..) underset(. .)O - CH_(3)),oxygen atom is central atom, and has the same hybridisation, yet they have different bond angles . Which one has greater bond angle ?Given reason ,
Answer» Solution :Dimethyl ether gas greater bond ANGLE than of WATER . Reaon . Central atom in both is `sp^(3)` -hybridised with two LONE pairs However, ELECTRON density on C of`CH_(3)`group is high because it is attached to three H-atoms `sigma ` - bonds and these electron pairs add to the elecronic charge density on carbon. HENCE , the repulsions betweenltbr. the two methyl groups is more than between two H-atoms.
