What is the predicted geometry of an S_N2 reaction transition state?

Question

Quizplus · Accepted Answer

S_N2 reaction involves a molecule with two substituents (SS and NS) and two lone pairs of electrons. According to VSEPR theory, this arrangement leads to a trigonal bipyramidal geometry with the two lone pairs occupying the axial positions and the two substituents occupying the equatorial positions. The transition state for this reaction would retain this overall geometry, with the atoms and lone pairs in transition state mimicking the positions they will occupy in the product. Therefore, the predicted geometry for the transition state of S_N2 reaction is trigonal bipyramidal.
