Question

give one example each for octahedral and trigonal bipyramidal​

Answer 1

Answer:

Trigonal BiPyramid Geometry. An example of trigonal bipyramid molecular geometry that results from five electron pair geometry is PCl5. The phosphorus has 5 valence electrons and thus needs 3 more electrons to complete its octet. However this is an example where five chlorine atoms present and the octet is expanded.

Examples of Octahedral Molecules

Sulfur hexafluoride is a common example of an octahedral molecule. The central sulfur atom is bonded to six fluoride atoms.
