Step 3: Use VSEPR table to find the shape. The distance from the bromine each axial fluorine is 1.81 Å and to the equatorial fluorine is 1.72 Å. A molecule’s shape depends on the number of bonded pairs (BP) and lone pairs (LP) around the central atom. The VSEPR model can be used to predict the structure of somewhat more complex molecules with no single central atom by treating them as linked AX m E n fragments. Fig. If none of the clouds is a lone pair, the molecular geometry will also be trigonal planar. No of lone pair = H–X–D = 4–0–3 = 1 As lone pair is present the structure will be distorted tetrahedral and without the lone pair structure is pyramidal.
