According to VSEPR theory , in the molecule of the type AB₃E₂ (where B and E represent number of bond pairs and lone pairs respectively) identify the position of lone pairs and bond pairs for the most stable structure of the molecule.

both lone pairs occupy equatorial positions , two bond pairs at equatorial position and one bond pair at axial position

both lone pairs occupy axial positions and three bond pairs are at equatorial position

two lone pairs at equatorial position, two bond pairs at axial position and one bond pair at equatorial position

one lone pair at axial position, one lone pair at equatorial position ,two bond pairs at equtorial position and one bond pair at axial position
