Answer:
AsCl5
Explanation:
Electronegativity of As= 2.18
Electronegativity of Cl= 3.16
∴ difference in their electronegativity is 0.98
According to difference in their electronegativity, the bond is polar (EN>0.4 are generally consider to be polar, while EN<0.4 bonds are considered to be nonpolar). However, AsCl5 has a trigonal pyramidal structure. It exhibits [tex]sp^{3} d[/tex] hybridization and has five equivalent hybrid orbitals directed towards the central of the trigonal pyramid. The five dipoles, which are arranged symmetrically around the central As atom, cancel each other hence resulting in a nonpolar molecule
