Give example and structure of (i) `AB_(3)L`
(ii) `AB_(5)` (iii) `AB_(2)L_(2)` type of molecules with example.

Explanation

(i) `AB_(3)L` : Number of bond pairs = 3
Number of lone pairs = 1
Shape Pyramidal
Example : `NH_(3)`
(ii) `AB_(5)` : Number of bond pairs = 5
Number of lone pairs = 0
Shape Trigonal bipyramidal
Example : `PCl_(5)`
(iii) `AB_(2)L_(2)` : Number of bond pairs = 2
Number of lone pairs = 2
Shape = Bent
Example : `H_(2)O`
