Answer:AsCl5Explanation:Electronegativity of As= 2.18Electronegativity of Cl= 3.16∴ difference in their electronegativity is0.98According 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 exhibitshybridization and has five equivalent hybrid orbitals directed towards the central of the trigonal pyramid. Thefive dipoles, which are arranged symmetrically around the central As atom,cancel each otherhence resulting in anonpolar molecule...
