Which bond is more polar B-CL or C-CL show working
To determine which bond is more polar between B-Cl and C-Cl, we need to look at the difference in electronegativity between the two atoms.
The electronegativity of boron (B) is 2.04, while the electronegativity of chlorine (Cl) is 3.16. The electronegativity difference between B and Cl is 1.12.
The electronegativity of carbon (C) is 2.55, which gives an electronegativity difference of 0.61 with Cl.
Since the electronegativity difference is greater in the B-Cl bond than in the C-Cl bond, the B-Cl bond is more polar.
