Why did stop adding tetraethyl lead to gasoline?
Tetraethyl lead is harmfull for the human beings, though it makes the car enigine more smooth to drive. In an extreme case, it can cause death to a person.
Why and when was lead phased out of gasoline as an additive?
Tetraethyl lead was phased out of gasoline in the United States starting in 1976 and ending in 1986. Leaded gasoline caused lead to be present in automotive exhaust, which caused an increase in the lead content in people's bloodstream, which tends to reduce I.Q. and increase antisocial behavior. Tetraethyl lead was used as an octane improver, and it also reduced valve seat wear. It damages catalytic converters, which are the primary emission control device in motor vehicles. Catalytic converters and hardened valve seats started being produced in 1975.
What is Tetraethyl lead used for?
petrol additive
Why tetraethyl lead is used in petrol?
To prevent knocking.
How many ethyl groups are there in lead tetra ethyl?
Tetraethyl lead has 4 ethyl groups attached to the lead atom.
Element added to gasoline in 70's?
Lead - in the form of Tetraethyl Lead

Is lead and tetraethyl lead the same?
no lead is an element and tetraethyl is an organic (or carbon) compound.
Do you need a fuel additive lead when using unleaded gasoline in your 1974 BMW 2002 automatic?
Yes, Lead is good. Your valves could be damaged by using unleaded. Try http://www.batterystuff.com/fuel-treatments/OS6q.html This is real tetraethyl lead, the good stuff.
What is the total number of atoms present in one molecule of tetraethyl lead?
Tetraethyl lead has 29 atoms in one molecule.

What are the uses of Lead Bromide?
When gasoline was leaded prior to 1995 (US) the combustion of gasoline containing lead tetraethyl was helped along by the addition of an organobromine compound, 1-2 dibromoethane, that formed lead bromide in combustion , which came out in the exhaust gas. Hardly a use but that was probably the only time most people would encounter this chemical.
How many ethyl groups are there in lead tetra ethyl?
Tetraethyl lead has 4 ethyl groups attached to the lead atom.
What is leaded gasoline?
This is petrol to which tetraethyl lead has been added to reduce knocking in the engine. Knocking is when combustion happens at the wrong time in the engine cycle giveing a kind of metallic "ping" sound.
How tetraethyl lead acts as knock inhibitor in gasoline?
Knock is an explosion that occurs too quickly from beginning to end. Think of a piano key struck and released right away. The explosion in a gas engine must last an optimum time. Lead is of course replaced by other chemicals now. Slower burning gasoline is that with the highest octane rating; necessary with more powerful engines.
