Question:
When TEL (Tetra Ethyl Lead) is added to petrol, then:
When TEL (Tetra Ethyl Lead) is added to petrol, then:
Show Hint
TEL was used historically to improve the performance of petrol engines, but it is now largely replaced due to environmental concerns.
Updated On: Apr 21, 2025
- it increases the B.P. of petrol
- it increases the anti-knocking rating
- it decreases the B.P. of petrol
- it decreased the anti-knocking rating
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Tetra Ethyl Lead (TEL) is an additive used in petrol to increase the anti-knocking rating. This means that TEL helps prevent engine knocking, thereby improving engine performance. TEL does not significantly affect the boiling point (B.P.) of petrol.
Thus, the correct answer is (B) it increases the anti-knocking rating.
Thus, the correct answer is (B) it increases the anti-knocking rating.
