Detailed Solution

Concept- A compound used to lessen engine knocking is known as an anti-knocking agent. The anti-knocking ingredient raises the fuel's octane rating. By increasing temperature and pressure, the anti-knocking agent aids in auto-ignition as well.
A chemical made of organo-lead is tetraethyl lead. Tetraethyl lead is a petrochemical additive that was initially blended with gasoline, which marked the beginning of its use as a patented octane rating booster that enabled engine compression to be significantly increased. General Motors research lab, which had spent years looking for an additive that might be both highly effective and reasonably priced, discovered TEL as an anti-knock.
Chloroethane and sodium lead alloys can react to create TEL. We can recover the product by employing steam distillation. Lead and sodium chloride are left behind as sludge. TEL is a well-known anti-knocking substance and is a colourless, viscous liquid.
Hence, the correct answer is option 1.
