Given the following information:
Tetraethyllead is a colourless, oily liquid with a faint fruity odor whose vapours form explosive mixtures with air. It burns with an orange-coloured flame with a green margin. Tetraethyllead has a specific gravity of 1.653 and boils at 200oC with decomposition.
The vapors are very toxic and fatal lead poisoning by ingestion, vapor inhalation, or skin absorption may occur. Open-cup flash-point is 120oC.
The formula for tetraethyllead is given as: (C2H5)4Pb
The structural formula is: C2H5
