And is its molecular polarity polar or nonpolar?

Question

CramX · Accepted Answer

Step 1: I'll solve this step by step, focusing on the bond polarity and molecular polarity of PCl₃.. Step 2: : Determine the Electronegativity Difference. - Phosphorus (P) electronegativity: 2.19 - Chlorine (Cl) electronegativity: 3.16 Step 3: : Analyze Bond Polarity. - The electronegativity difference of 0.97 indicates a polar covalent bond - Chlorine is more electronegative, so it will pull electron density away from phosphorus - Each P-Cl bond will have a partial negative charge on chlorine and a partial positive charge on phosphorus Step 4: : Examine Molecular Geometry. - PCl₃ has a trigonal pyramidal molecular geometry - The three chlorine atoms are not symmetrically arranged around the phosphorus - This asymmetric arrangement allows for net dipole moment Step 5: : Determine Molecular Polarity. - Because the P-Cl bonds are polar and the molecular geometry is asymmetric - The individual bond dipoles do not cancel out - Therefore, PCl₃ is a polar molecule Final Answer: - Bond Type: Polar Covalent - Molecular Polarity: Polar
