Question

Tetraethyl lead is a Petroleum additive.
A. True
B. False

Answer 1

In order to answer the question, first we should get the knowledge about the composition or the making structure of the tetraethyl lead. And then on the basis of its structure and composition, we should judge its role in fuel additives.

Complete answer: Yes, Tetraethyl lead is a Petroleum additive.
Tetraethyl lead, ${({C_2}{H_5})_4}Pb$ , is a petro-fuel added substance, first being blended in with gas starting during the 1920s as a protected octane rating supporter that permitted motor pressure to be raised considerably. This, in turn, caused increased vehicle performance and fuel economy.
It is used as an antiknock compound in gasoline. An antiknock agent is added to gasoline. It reduces engine knocking and increases the fuel’s octane rating. A gas energized responding motor requires fuel of adequate octane rating to prevent uncontrolled ignition known as motor knocking (knock or ping). Antiknock specialists permit the utilization of higher pressure proportions for more prominent effectiveness and pinnacle power. Adding fluctuating measures of added substances, for example, low rate TEL or high rate ethanol to fuel permitted simple economical control of octane appraisals. TEL offered the business bit of leeway of being economically productive on the grounds that its utilization for this reason could be protected.

Hence, the correct option is A,True.

Note: Tetraethyl lead is highly toxic, with as little as 6-15mL being enough to induce severe lead poisoning.[63] The hazards of TEL's lead content are heightened due to the compound's volatility and high lipophilicity, enabling it to easily cross the blood-brain barrier and accumulate in the limbic system, frontal cortex, and hippocampus, making chelation therapy ineffective.
