In BrF_3 molecule , the lone pairs occupy equatorial positions to minimise

In SF_4 molecule, the lone pair of electrons occupy equatorial position in preference to axial position, why ? Predict shape of the molecule?

In SF_(4) molecule, the lone pair of electrons occupies an equatorial position, rather than axial position, in the overal trigonal bipyramidal arrangement. Wy?
