Question

The bond angle in H2O between two OH bond is104degrees 31' ,why can't it be 180degrees​

Answer 1

Answer:

H2O hybridization is SP3 . it has angular shape or bent V shape . due Vsepr theory.and presence of two unpaired electrons it possess the bond angle 104 degrees 31'

Answer 2

Answer:

The bond angle (HOH) in water molecule is 104°31' instead of 90° because of the presence of lone pair - lone pair repulsion.

So, the two hydrogen atoms are bonded to one oxygen atom through hydrogen bonds.
