If you have a Yahoo or AOL account, you must accept these terms. Note: Hydrocarbon becomes saturated when it contains C-C single bond and hydrocarbon is unsaturated when carbon, double or triple bonds are present. Steam lowers the partial pressure of high molecular aromatics, reduces condensation reactions It also helps to partially remove coke in the pipes. triple bond between the two carbon atoms in an Ethin molecule is completely non-polar and the bonds between carbon and hydrogen are generally considered non-polar, although in the presence of a radical initiator (such as light or heat), a weak polar grade ethane is added to form 2-bromoethane as a main product in a free radical mechanism. High yields of biobased ethylene can be obtained by dehydration of ethanol vapor with a catalyst comprising a mixture of magnesia, alumina and silica at 600-750 K.
