(b) \(\text{AsCl}_{5}\): Electron-domain geometry is trigonal bipyramidal, and molecular geometry is trigonal bipyramidal. (c) \(\text{NO}_{2}^{-}\): Electron-domain geometry is trigonal planar, and molecular geometry is bent. (d) \(\text{CS}_{2}\): Electron-domain geometry is linear, and molecular geometry is linear. (e) \(\text{SF}_{4}\): Electron-domain geometry is octahedral, and molecular geometry is tetragonal pyramidal (seesaw). (f) \(\text{BrF}_{5}\): Electron-domain geometry is octahedral, and molecular geometry is square pyramidal.
