Required Conversion:
=> 1-Bromoethane to Ethane gas.
Mechanism of reaction that has to take place:
=> Here, the bromine atom attached to the carbon atom in 1-Bromoethane must be removed and replaced with a hydrogen atom.
=> Obviously, this is an example of reduction, as an electronegative element Bromine is removed and Hydrogen is added.
=> This can only be done in the presence of nascent hydrogen gas as one of the nascent hydrogen atoms will immediately attack the bromine atom, replace it and the other will combine with it to form hydrogen bromide.
=> Thus, an alloy called as Zn-Cu couple (Zinc-copper couple) is used along with ethyl alcohol, this produces atoms of nascent hydrogen.
Equation for required conversion:
C2H5Br + 2 [H] (nascent hydrogen) -------> C2H6(ethane) + HBr
In short:
=> A Zn-Cu couple (alloy) is:
- is introduced into Bromoethane in the presence of alcohol (C2H5OH)
- this forms bubbles of Ethane (C2H6) gas that can
- be collected by the downward displacement of water.
More to know:
=> This reaction can similarly be used with other alkyl halides to give alkanes.
