How many of the following molecules are with non-zero net dipole moment,

NH3,HCl,H2O,BeF2,BH3,CCl4{NH}_{3}, HCl, {H}_{2}O, {BeF}_{2}, {BH}_{3}, {CCl}_{4}

Correct answer

3

Step-by-step solution

Among the given molecules BeF2,CCl4{BeF}_{2}, {CCl}_{4} and BH3{BH}_{3} has zero dipole moment. BeF2{BeF}_{2} has linear structure and BH3{BH}_{3} has symmetrical trigonal planar structure and CCl4{CCl}_{4} also has symmetrical tetrahedral structure.

NH3,HCl,H2O{NH}_{3}, HCl, {H}_{2}O have non-symmetrical structure.

Hence, their net dipole moment is not zero
