How many of the following molecules are with non-zero net dipole moment, NH 3   , HCl ,   H 2 O   ,   BeF 2 ,   BH 3 ,   CCl 4

Step-by-step solution

Among the given molecules BeF 2 ,   CCl 4 and BH 3 has zero dipole moment. BeF 2 has linear structure and BH 3 has symmetrical trigonal planar structure and CCl 4 also has symmetrical tetrahedral structure. NH 3   , HCl ,   H 2 O have non-symmetrical structure. Hence, their net dipole moment is not zero
