Question

H – O – H bond angle in water is [ ]

a) 109° 28| b) 120° c) 180° d) 104.5°​

Answer 1

Answer:

d)104.5 degree.

H2O.BOND ANGLE.IS 104.5 DEGREE

Answer 2

Answer:

option (d)

Explanation:

oxygen molecule have 6 electrons and hydrogen bond with oxygen .after bonding oxygen would have leaving 2 lone pairs of electrons.

Then oxygen would have 4 bonds which gives bond angle 109.5 degree.

each lone pair of electrons reduce 2.5 degree because repel bonded electrons pairs more strongly .

109.5-5=104.5.
