Question

Why the bond angle in water is 104° 31' instead of 109° 28' ?​

Answer 1

hi,

water molecule oxygen atom has hybridization type

sp3,so the expected bond angle is 109.28'but

The bond angle of water is 104.28' becoz oxygen atom has two lone pair of electrons which repulsive force increases and push the bond to decrease the angle to 104.31' according to VSEPR the.
