Question: Bond angle is minimum in...
Bond angle is minimum in
A
H2O
B
CO2
C
NH3
D
CH4
Answer
H2O
Explanation
Solution
In CO2 molecule, structure is linear O = C = O. So bond angle is 180°
In H2O, NH3 & CH4 the central atom is sp3 hybridised
In CH4 4 bond pair of electrons and no lone pair of electron is present.
In NH3 3 bond pair of electron and 1 lone pair of electron is present.
In H2O 2 bond pair of electron and 2 lone pair of electron is present.
Greater is no. of lone pair greater is the lone pair bond pair repulsion smaller is the bond angle.
So bond angle is least in case of H2O
