1. Find the electronegativity values:
* Aluminum (Al): 1.61
* Chlorine (Cl): 3.16
2. Calculate the difference:
* Electronegativity difference = 3.16 - 1.61 = 1.55
Conclusion:
The electronegativity difference in an Al-Cl bond in Aluminum Chloride is 1.55. This indicates that the bond is polar covalent. The chlorine atom has a higher electronegativity, meaning it attracts the shared electrons more strongly, resulting in a partial negative charge on the chlorine atom and a partial positive charge on the aluminum atom.
