The constituents of petroleum and natural gas, petroleum “fractions” and the explanation corresponding to their uses are to be stated. The meaning of cracking petroleum and the reason as to why the cracking of petroleum is done are to be stated. The uses of tetraethyl lead and the reason of reduction in its use are to be stated. The explanation corresponding to the greenhouse effect and the reason as to why scientists are concerned about it are to be stated. Concept Introduction: Millions of years ago, dead organisms were embedded in the sea due to various tragedies such as flood and earthquake. These dead organisms were completely shielded with sand and clay. The absence of oxygen, high pressure and temperature converted them into natural gas and petroleum. In this way, the formation of petroleum takes place. Refining is the process, which is used to purify the desired substances. It removes the impurities from petroleum and it is followed by distillation that aid in the isolation of different fractions of petroleum.
