Answer and Explanation: The answer is c. trigonal pyramidal. Some of the simple ones are pretty much like they are on paper - but for most, we need to learn actual 3D structures, the nomenclature of it, and all the other goodness that three dimensions brings. Trigonal Planar. But in trigonal pyramidal there’s bond- bond and bond- lone pair repulsion.

Jmol.jmolLink(jmolApplet0,"Frame Next","Next \u23ED");Jmol.jmolHtml('    ');Jmol.jmolLink(jmolApplet0,"Frame Prev","Prev \u23EE"); What is the name of AX3 VSEPR shape? The shape of the orbitals is trigonal bipyramidal.Since there is an atom at the end of each orbital, the shape of the molecule is also trigonal bipyramidal. In an ideal trigonal planar species, all three ligands are identical and all bond angles are 120°. Total electrons = 28. Gravity. The elec-tronic structure is rather quasi-two-dimensional and thus Lewis structures are a good representation of the structure of a molecule in 2 dimensions. PF2Cl3 has a trigonal bipyramidal structure where the chlorine atoms are arranged evenly around the centre so it is symmetrical and therefore non-polar overall. The known geometries for a molecule are tetrahedral, bent, trigonal planar, trigonal pyramidal, and trigonal bipyramidal. The Lewis diagram is as follows: seesaw.
