A catalyst in burning fossil fuel
An antioxidant
A reductant
An antiknock compound
Answer is Right!
Answer is Wrong!
The correct answer is D. Tetraethyl lead (TEL) is an antiknock compound. It is added to gasoline to prevent engine knocking, which can damage the engine. TEL works by reducing the tendency of the fuel-air mixture to detonate spontaneously. It does this by increasing the octane rating of the fuel, which is a measure of its resistance to knocking.
A catalyst is a substance that increases the rate of a chemical reaction without itself being consumed. An antioxidant is a substance that prevents or slows down the oxidation of other substances. A reductant is a substance that donates electrons to another substance.
TEL is not a catalyst, antioxidant, or reductant. It is an antiknock compound.
