Which is polar HCl or HF

Which one is polar HCl or HF?

E

Expert

Verified

This question is pretty simple if we have an electro negativity chart:
Chlorine's Electronegativity is: 3.0
Florine's Electronegativity is : 4.0
Hydrogen's Electronegativity: 2.1
and
HCl: 3.0-2.1= .9 (means Slightly polar)
HF: 4.0-2.1= 1.9 (means Much more polar)
