Question

In the chlorination, substitution reaction of propane two isomeric products containing one chlorine atom are obtained. Draw their structural formulae and give their IUPAC names.

Accepted Answer

Substitution reaction is a chemical reaction in which an atom or group of atoms replaces the atoms present in the compound. Chlorination in the presence of sunlight gives the free radical substitution reaction in which the hydrogen atom is replaced by the chlorine atom. When propane and chlorine react in the presence of light the free radical substitution reaction takes place as follows: There is a possibility to form 2 isomers with the same molecular formula and different structures.

$\underset{Propane}{{CH}_{3} - {CH}_{2} - {CH}_{3}} + \underset{Chlorine}{{Cl}_{2}} \overset{light}{\to} \underset{2 - chloropropane}{{CH}_{3} - CH (Cl) - {CH}_{3}} + \underset{Hydrogen chloride}{HCl}$

The structural formula of 2-chloropropane is as follows:

$\underset{Propane}{{CH}_{3} - {CH}_{2} - {CH}_{3}} + \underset{Chlorine}{{Cl}_{2}} \overset{light}{\to} \underset{1 - chloropropane}{{CH}_{3} - {CH}_{2} - {CH}_{2} Cl} + \underset{Hydrogen chloride}{HCl}$

The structural formula of 1-chloropropane is as follows:

In the chlorination, substitution reaction of propane two isomeric products containing one chlorine atom are obtained. Draw their structural formulae and give their IUPAC names.
