  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

Answer:

     (i-e) (ii-c) (iii-d) (iv-a, b).

\[BF_{4}^{-}\]	\[s{{p}^{3}}\]-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
