Examples of how to use “trigonal” in a sentence from the Cambridge Dictionary Labs The atoms of trigonal bipyramidal molecules are arranged on two planes that intersect at the central atom. The two planes form a 90 degree angle. The axial plane consists of the central atom and two of the surrounding atoms; they have a linear arrangement, meaning that they form a straight line. The pentagonal bipyramid is a case where bond angles surrounding an atom are not identical (see also trigonal bipyramidal … they all have a trigonal bipyramidal arrangement of electron pairs around the central atom. The electron distribution is based on 5 sites, so a trigonal bipyramidal distribution is used. Here's the trigonal bipyramidal geometry: Now the angles are exactly what we expect from VSEPR. Choose the molecule that is incorrectly matched with the electronic geometry about the central atom. The trigonal bipyramidal, abbreviated TBP, is found when there are 5 bonds and 0 lone pairs (right). The angles between the equatorial positions (the 3 bonds in the trigonal plane) are 120°, while the angle between the axial positions (the 2 bonds on either side of the trigonal plane) and the trigonal plane is 90°.
