Arrange the following bonds in order of increasing
polarity:
O-Cl, C-Cl, H-Cl, and F-Cl
O-Cl < C-Cl < H-Cl < F-Cl |
|
C-Cl < O-Cl < H-Cl < F-Cl |
|
C-Cl < O-Cl < F-Cl < H-Cl |
|
O-Cl < C-Cl < F-Cl < H-Cl |
|
H-Cl < F-Cl < C-Cl < O-Cl |
If the electronegativity difference is more then the polarity of the bond is more.
The electronegativity of O is 3.5
Cl is 3.0
C is 2.5
H is 2.1
F is 4.0
The electronegativity difference between O & Cl in O-Cl is 0.5
The electronegativity difference between C & Cl in C-Cl is 0.5
The electronegativity difference between H & Cl in H-Cl is 0.9
The electronegativity difference between F & Cl in F-Cl is 1.0
Since the electronegativity difference between F & Cl in F-Cl is more so the order of increasing polarity is:
C-Cl < O-Cl < H-Cl < F-Cl
