Question

Give example and structure of

1. AB₃L 

2. AB₅ 

3. AB₂L₂

type of molecules with example.

Answer 1

1. AB₃L

Number of bond pairs = 3 

Number of lone pairs = 1 

Shape = Pyramidal

Example – NH₃

2. AB₅

Number of bond pairs = 5 

Number of lone pairs = 0 

Shape = Trigonal bipyramidal

Example- PClC₅

3. AB₂L₂

Number of bond pairs = 2 

Number of lone pairs = 2 

Shape = Bent

Example – H₂O
