Step-by-step solution
XeF _2 2 sigma bonds and 3 lone pairs on Xe , number of hybrid orbitals =5, sp ^3 ~d hybridisation geometry will be trigonal bipyramidal. P - 5 XeF _4 4 sigma bonds and 2 lone pairs on Xe , number of hybrid orbitals =6, sp ^3 ~d ^2 hybridisation , geometry will be octahedral. Q - 3 XeO _3 3 sigma bonds and 1 lone pairs on Xe , number of hybrid orbitals =4, sp ^3 hybridisation , geometry will be tetrahedral. R - 2 XeO _3 ~F _2 5 sigma bonds and 0 lone pairs on Xe , number of hybrid orbitals =5, sp ^3 ~d hybridisation , geometry will be trigonal bipyramidal. S - 4
