I THINK IT'S 2.5
The third one beacuse if you count all the atoms of every one you will find that one the left side, you have 3 h and on the right you have 2 h
Answer:
D. C → Cl electronegativity difference > 0.5
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
A homogeneous mixture, the substances are uniformly distributed throughout the mixture
