We have step-by-step solutions for your textbooks written by Bartleby experts! a) 90 degrees. The shape of the orbitals is octahedral. Also, it has no dipole moment and the electron group geometry is octahedral. For AX5E molecules like BrF5 (square pyramidal), we observe a small diminution of the angle between bonds Br-Feq and Br-Fax (85º instead of 90º) due to a higher volume occupied by the non-bonding pair and the axial bond is longer that the equatorial ones. The shape is polar since it is asymmterical. The angle between the atoms will be less than the angle of a tetrahedron (109 o). trigonal pyramidal trigonal planar Ideal bond angle:_____ degrees 12. e) linear . The square pyramidal structure of IF5 is very easily explained using VSEPR Theory.
