A) Both I_2Cl_6 and Al_2Cl_6 have 3C\\, -\\, 4e^- bonds. Hence, option A is correct.B) In I_2Cl_6 , the central I atom undergoes sp^3d^2 hybridization and in Al_2Cl_6 , the central Al atom undergoes sp^3 hybridization. Thus, the option B is incorrect.C) I_2Cl_6 is planar and Al_2Cl_6 is non planar. Thus, the option C is incorrect.
