1.	{:("List-I"," ""List-II"),((A)SiF_(4),P."Lewis acid"),((B)CO_(2),Q."Lewis base"),((C) SO_(2),R."Bronstead acid"),((D)NH_(3),S."Bronstead base"):}
Answer» Solution :` SiF_4` has vacant d- ORBITALS but cannot add or give `H^(+) ` ` CO_2 ` cannot add or give ` H^(+) ` ` SO_2`has lone PAIR ` NH_3 ` can give and TAKE `H^(+) `and has lone pair
