The fact that there are only two chlorines, and that both of the chlorines is in an ortho position would tend to make this congener of PCB less toxic than the case in which the congener contains 6 chlorines, but chlorines are lacking in all of the … Web1.2 What are properties of PCBs? PCBs, or polychlorinated biphenyls, are a class of man-made organic chemicals. Each PCB molecule contains two phenyl rings.A phenyl ring is a ring of 6 carbon atoms to which hydrogen atoms are attached. In PCBs, chlorine atoms replace some of these hydrogen atoms. Chlorine atoms may be present at some or all of …
