Vedclass · Answer

(B) The overall value of the dipole moment of a polar molecule depends on its geometry and shape,i.e.,the vectorial addition of the dipole moments of the constituent bonds.Water $(H_2O)$ has an angular structure with a bond angle of $105^{\circ}$,which results in a net dipole moment.However,$BeF_2$ is a linear molecule where the dipole moments of the two $Be-F$ bonds are equal in magnitude and opposite in direction,thus canceling each other out,resulting in a net dipole moment of zero.

$H_2O$ is dipolar,whereas $BeF_2$ is not. It is because
