(A) In $H_2O$,the $O-H$ bond dipoles are equal in magnitude,but they are oriented at an angle of $104.5^{\circ}$ to each other.Because of the bent geometry,the vector sum of the bond dipoles is not zero.Therefore,$H_2O$ possesses a net dipole moment.In contrast,$BF_3$,$C_6H_6$,and $CCl_4$ have symmetric structures (trigonal planar,planar hexagonal,and tetrahedral,respectively) where the individual bond dipoles cancel each other out,resulting in a net dipole moment of zero.
