Question

Predidt the direction and the relative value of the dipole moment of the following bond: C-Cl

A. C ← CL electronegativity difference < 0.5
B. C ← CL electronegativity difference > 0.5
C. C → Cl electronegativity difference < 0.5
D. C → Cl electronegativity difference > 0.5

Answer 1

D. C → Cl electronegativity difference > 0.5

Step-by-step explanation:

The electro negativity of an atom in a compound refers to its ability to attract the electrons of a bond towards itself.

On the Pauling's scale, carbon has an electro negativity value of 2.55 while that of chlorine is 3.16. The difference in electro negativity between the both atoms is about 0.61.

The dipole is aslways directed towards the more electronegative atom. Hence the direction is ; C → Cl
