Biphynyls are a class of compounds with two phenyl rings attached by C − C X ′ carbons in each phenyl ring (See Figure A ): The phenyl rings can rotate around this C − C X ′ bond (acts as an axis). Keep in mind that any molecule capable of rotating one part of it around fixed axis (a bond) is never planner.
WebPCB is the commonly used abbreviation for a group of organochlorine compounds referred to as polychlorinated biphenyls or polychlorobiphenyls [1]. These materials, represented by the general structure shown in Figure 1 and the formula C 12H 10–xCl x, are based structurally on a biphenyl ring system to which 1–10 chlorine atoms may be attached.
