JEE MAIN - Chemistry (2022 - 30th June Morning Shift - No. 16)
Amongst the following, the number of molecule/(s) having net resultant dipole moment is ____________.
NF3, BF3, BeF2, CHCl3, H2S, SiF4, CCl4, PF5
Answer
3
Explanation
Symmetrical molecules have zero dipole moment like $\mathrm{BF}_{3}$, $\mathrm{BeF}_{2}, \mathrm{SiF}_{4}, \mathrm{CCl}_{4}$ and $\mathrm{PF}_{5}$.
Unsymmetrical molecules have net diploe moment like $-\mathrm{NF}_3$, $\mathrm{CHCl}_3$ and $\mathrm{H}_2 \mathrm{S}$
