So this is the Lewis structure for this molecule. c. Graph not available All 18 electrons are used. For trigonal pyramidal geometry the bond angle is slightly less than 109.5 degrees, around 107 degrees. Due to this repulsion force, the lone pairs tend to go far from each other in the plane. Both hydrogen atoms need only two electrons while nitrogen needs 8 electrons to complete duplet and octet respectively. XeOF4 is a molecule that adopts this structure. For bent molecular geometry when the electron-pair geometry is tetrahedral the bond angle is around 105 degrees.
