The organic compound used as anti knock agent in petroleum
Answers
Solution :-
Tetraethyl lead [pb(CH₂CH₃)₄] is the organic compound which is used as anti knock agent in petrol.
Petrol is a mixture of compounds of carbon and hydrogen called hydrocarbons. Mos of the hydrocarbons in petrol are like alkanes. In modern car engines, the petrol vapor-air mixture is highly compressed before it is sparkled, in order to get the maximum energy from the burning fuel. However, some hydrocarbons tend to ignite under pressure before they are sparkled, so that the engine runs roughly. This is known as "knocking".
In 1922, the American named Thomas Midgely found that tetraethyl lead was put into petrol. Particles of lead and lead oxide are formed on combustion.This helps the petrol to burn more slowly and smoothly, preventing knocking and giving higher octane ratings. Using higher-octane leaded petrol meant that more powerful high-compression engines could be built.
Tetraethyl lead [pb(CH₂CH₃)₄] is the natural compound which is utilized as against thump specialist in oil.
Oil is a blend of mixes of carbon and hydrogen called hydrocarbons. Mos of the hydrocarbons in petroleum resemble alkanes. In present day vehicle motors, the petroleum vapor-air blend is exceedingly compacted before it is shone, so as to get the most extreme vitality from the consuming fuel. In any case, a few hydrocarbons will in general touch off under strain before they are shone, with the goal that the motor runs generally. This is known as "thumping".
In 1922, the American named Thomas Midgely discovered that tetraethyl lead was put into petroleum. Particles of lead and lead oxide are framed on combustion.This encourages the oil to consume all the more gradually and easily, counteracting thumping and giving higher octane appraisals. Utilizing higher-octane leaded petroleum implied that all the more incredible high-pressure motors could be fabricated.
