Multiple choice

Which of the following sets of molecular ions, have T-shaped geometry?

  1. H3O+, AlCl3 and NO2-

  2. ICl2-, I3- and ClF2-

  3. NF3, PCl3 and SO3

  4. NH2-, BCl3 and ICl2+

  5. BrF3, IF3 and XeOF2

E Correct answer
Explanation

This option is correct because for minimum repulsion between the electron pairs two lone pairs occupy the basal positions and out of three bond pairs, one occupies basal position and two along axial positions. Thus according to VSEPR theory all molecules, IF3, XeOF2 and BrF3 possess T-shaped geometry.
