  2. Ethyl sodium

  3. Ethane

  4. Wthene

Show answer
Correct Option: A
Explanation:

When we treat ethyl bromide with lead sodium alloy we get tetra ethyl lead [TEL]


$4NaPb+4CH _3CH _2Br\longrightarrow \overset {\uparrow Tetraethyllead}{(CH _3CH _2) _4Pb}+4NaCl+3Pb$

TEL is used to increase their efficiency and performance.
