A laboratory technician measures the polarity of various gases. Despite containing highly polar B-F bonds, which molecule shows a net dipole moment of zero?
Q1. A laboratory technician measures the polarity of various gases. Despite containing highly polar B-F bonds, which molecule shows a net dipole moment of zero?
Answer: BF3
Explanation: BF3 has zero dipole moment due to its symmetrical trigonal planar geometry; NF3 is tempting but its lone pair prevents symmetry cancellation.
