VSEPR of H2O

Postby Hai-Lin Yeh 1J » Fri Nov 09, 2018 1:22 pm

Since BeCl2 is linear and the central atom has 2 bonding pair, does that mean H2O is also linear and has 180 degree bond angle? If not, why?

H2O is not linear because in addition to its 2 bonding pair electrons, it also has 2 lone pair electrons that distort the shape of the atom to resemble an exaggerated tetrahedron. This explains the bent shape of H2O and the presence of a 104.5 degree H-O-H bond angle.
