Question

Quizplus · Accepted Answer

The electron pair geometry of trigonal planar is formed when there are three electron pairs around the central atom in a flat, triangular arrangement. Among the given compounds, only BF3 (ii) has trigonal planar electron pair geometry as it has three bonding pairs of electrons around the central boron atom with no lone pair of electrons. NFS, PH3, and IO3- have tetrahedral, pyramidal, and trigonal bipyramidal electron pair geometries respectively.
