• # question_answer 82) In the following questions more than one correlation is possible between options of column I and column II. Make as many correlations as you can. Match the species given in column I with the properties mentioned in column II.   Column I Column II   (i) $BF_{4}^{-}$ (a) Oxidation state of central atom is +4  (ii) $AlC{{l}_{3}}$ (b) Strong oxidising agent  (iii) $SnO$ (c) Lewis acid  (iv) $Pb{{O}_{2}}$ (d) Can be further oxidised   (e) Tetrahedral shape

 $BF_{4}^{-}$ $s{{p}^{3}}$-hybridisation Tetrahedral shape $AlC{{l}_{3}}$ Electron deficient Lewis acid $SnO$ $+4$state is more stable than +2 Can be further oxidised $Pb{{O}_{2}}$ $x-4=0,x=4,$i.e., oxid, state 4 However, in lead +2 oxidation state is more stable than +4 state acts as strong oxidising agent
