Based on molecular geometry and vector addition, which of the following molecules possess a net non- — Chemical Bonding Chemistry Question

💡 Solution & Explanation

$XeF_4$ is square planar and $PCl_3F_2$ is trigonal bipyramidal (with $F$ atoms at axial positions); both are highly symmetrical, leading to dipole moment vectors canceling out ($\mu = 0$). $ClF_3$ (T-shaped) and $SF_4$ (See-saw) are asymmetrical due to lone pairs, resulting in a net dipole moment.
