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

Question

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

TestHub · Accepted Answer

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
