Explain Wurtz reaction with an example ~​
Deffense [45]

Wurtz reaction is a special type of organic reaction involving the synthesis of aliphatic hydrocarbons from two molecules of an alkyl halide and two atoms of sodium in the presence of dry ether solution

Please bear in mind that wurtz reaction fails whenever tertiary alkyl halides are used.

An example of Wurtz reaction is given below:

2R – X + 2Na → R–R + 2Na + X−

<h3>What are organic compounds?</h3>

Organic compounds can simply be defined as those classes of organic molecules which contain carbon atoms covalently bonded to hydrogen atoms (C-H bonds).

Below are some few general characteristics of organic compounds:

  • All organic compounds contain carbon.

  • Most of them are flammable.

  • They are all soluble in non-polar solvents

  • Most organic compounds / substances are covalently bonded molecules

Some classes of organic compounds are:

  • Alkanes
  • Alkenes
  • Alkenes

So therefore, Wurtz reaction is a special type of organic reaction involving the synthesis of aliphatic hydrocarbons from two molecules of an alkyl halide and two atoms of sodium in the presence of dry ether solution
