Expert
There are around 30 electrons in the benzene. This comprises 24 carbon electrons and 6 hydrogen electrons. There are 12 electrons shared among C and H, and 18 among C and C. (6 electrons in up ring, 6 in the down ring and 6 among C and C).
The occurrence of different phases of a one component system can be shown on a pressure temperature. The phases present in a one line system at various temperatures can be conveniently presented on a P- versus-T diagram. An example is pro
