Match List I with List II and select the correct answer: {:(,"List I(ion)",1,"List II (Shapes)"),(A,ICl_(2)^(-),1,"Linear"),(B,BrF_(2)^(+),2,"Pyramidal"),(C,CIF_(4)^(-),3,"Tetrahedral"),(D,AICl_(4)^(-),4,"Square planar"),(,,5,"Angular"):}

Answer»

`{:(A,B,C,D),(1,2,4,5):}`
`{:(A,B,C,D),(4,5,2,3):}`
`{:(A,B,C,D),(1,2,4,3):}`
`{:(A,B,C,D),(5,1,3,4):}`

Solution :`ICI_(2)^(-) rArr 2bp+bp+3lp` (thus `SP^(3)d` hybridisation) = LINEAR geometry
`BfF_(2)^(+) rArr 2bp+2lp` (thus `sp^(3)` hybridisation)= pyramidal geometry)
`CiF_(4)^(-) rArr 4bp+2lp`( thus `sp^(2)d^(2)` hybridisation) = square plaanar geometry)
`AlCl_(4)^(-) rArr 4bp+0lp` (thus `sp^(3)` hybridisation) = tetrahedral geometry
