Question

In the following, which central atom has different hybridization than others
a OF2
b Cl20
c H2O
d SO2

Answer 1

(a) Both XeF  

2

​  

 and CO  

2

​  

 are linear in shape.

XeF  

2

​  

 undergoes sp  

3

d  

2

 hybridization and  and CO  

2

​  

 undergoes sp hybridization.

(b) Both I  

3

−

​  

 and HgCl  

2

​  

 are linear in shape.

I  

3

−

​  

 undergoes sp  

3

 hybridization and  HgCl  

2

​  

 undergoes sp hybridization .

(c) Both OCl  

−

 and CO are linear in shape.

OCl  

−

 undergoes sp  

3

 hybridization and  CO undergoes sp hybridization.

(d) Both SO  

2

​  

 and OCl  

2

​  

 are angular in shape.

SO  

2

​  

 undergoes sp  

2

 hybridization and  OCl  

2

​  

 undergoes sp  

3

 hybridization.

Thus, all the four options are correct.

Answer 2

Answer:

• In OF2 two lone pairs of Oxygen and 2 bond pairs with Flourine gives sp3
• In Cl2O,H2o it is same
• but in SO2, the situation here is different, here two oxygen atoms forms double bonds with sulphur and one lone pair is present so it form sp2 hybridization
