Remember, lewis structures are 2D models of a 3D object, so what is drawn may not be what it actually looks like. Wherever you place the lone pairs, they will be at 109.5 degrees from everything else, including the other lone pair, making them adjacent.

XeF 4 consists of two lone pair electrons. XeF4 Molecular Geometry And Bond Angles The lone pairs of Xenon lie in the perpendicular plane in an octahedral arrangement. The first replacement is arbitrary; in an octahedral geometry, all the positions are equivalent. To get from S F X 6 to S F X 4 X 2 −, we need to replace two fluorines with lone pairs.
