Answer 2

Is the answer C?

Answer 3

Polar ranges from difference of electronegativity of 0.4-1.9

C has a polarity of 1.7, which is the highest of the list. Yes, it's C

Answer 4

Ok thanks!

Answer 5

It was wrong...

Answer 6

Uhh..polar covalent from 0.4 to 1.9..not sure what I did wrong. Does it tell you what was the right answer?

Answer 7

A. HCl was the right answer

Answer 8

Oh, they must of let H2 in H2S just be H sort of like a diatomic molecule...then it would have a less eletronegativity
