Step 1:I'll solve this problem step by step, explaining the polarity of HCl:
Step 2:: Understand Molecular Structure
- HCl consists of hydrogen (H) and chlorine (Cl) atoms - The molecule forms a simple diatomic structure - We need to examine the electronegativity difference between H and Cl
Step 3:: Electronegativity Comparison
- Electronegativity difference: $$3.16 - 2.20 = 0.96
- Chlorine electronegativity: 3.16
Step 4:: Determine Polarity Criteria
- An electronegativity difference > $$0.5$$ indicates a polar bond
- The more electronegative atom (Cl) pulls electron density away from H - This creates a partial negative charge on Cl and partial positive charge on H
Step 5:: Molecular Geometry
- Linear molecular geometry - Unequal electron distribution creates a permanent dipole moment - The molecule has a distinct positive and negative end
Final Answer
HCl is a POLAR molecule due to the significant electronegativity difference between H and Cl, which creates an uneven electron distribution and a permanent dipole moment.
