Which Molecule is More Polar: Br2 or HBr?

Click For Summary
SUMMARY

The discussion centers on the polarity of the molecules Br2 (bromine) and HBr (hydrogen bromide). Br2 is a nonpolar molecule due to its symmetrical linear shape and equal electronegativity of the bromine atoms. In contrast, HBr is polar because of the significant difference in electronegativity between hydrogen and bromine, resulting in a dipole moment that points from hydrogen to bromine. Therefore, HBr is definitively more polar than Br2.

PREREQUISITES
  • Understanding of molecular geometry and shapes
  • Knowledge of electronegativity and its role in polarity
  • Familiarity with dipole moments
  • Basic concepts of chemical bonding
NEXT STEPS
  • Research molecular geometry using VSEPR theory
  • Study electronegativity values of common elements
  • Learn about dipole moments and their calculation
  • Explore the implications of molecular polarity in chemical reactions
USEFUL FOR

Chemistry students, educators, and anyone interested in molecular structure and polarity analysis.

1. Determine the shapes of Br2 (2 Bromine atoms) and HBr. Which is more polar and why?



2. No equations.



3. Okay, I know that Br2 and HBr molecule shapes are linear (I know how to draw them) but I do not get how to find which one is more polar. :confused:
