Vedclass · Answer

(A) $H_2O$ has a bent (angular) geometry due to the presence of two lone pairs on the central oxygen atom,resulting in a non-zero net dipole moment. $BeF_2$ has a linear geometry ($sp$ hybridization) where the two $Be-F$ bond dipoles are equal in magnitude and opposite in direction,canceling each other out to result in a net dipole moment of zero.

$H_2O$ is polar,whereas $BeF_2$ is not. This is because ........
