xef4 shape and bond angle
Bond distances are measured in Ångstroms (1 Å = 10 –10 m) or picometers (1 pm = 10 –12 m, 100 pm = 1 Å). Therefore this is an octahedral shape, with 90 degree angles between each bond and lone pair of electrons. What's the value of the smallest bond angle in XeF4. This time the bond angle closes slightly more to 104°, because of the repulsion of the two lone pairs. How long will the footprints on the moon last? Have you registered for the PRE-JEE MAIN PRE-AIPMT 2016?

So when asked to describe the shape of a molecule we must respond with a molecular geometry. That will give you a linear molecule with the geometry of electrons/bonds around the Br atoms in a trigonal bipyramid arrangement. Due to VSEPR (valence shell electron pair repulsion) theory, the most energetically stable form of XeF4 will form, with the lone pairs as far away from each other as possible, hence forming the shape seen. The bond angle of F-Xe-F is 180 degrees. Get your answers by asking now.
