Which one is polar HCl or HF?
Expert
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)
