Question 1 Report
On cracking medicinal paraffin, a gas is evolved which gives a pop sound with a lighted splinter and an oily liquid which decolourizes bromine solution is also obtained. The products of the cracking are ?
Answer Details
When medicinal paraffin is cracked, two products are obtained - a gas and an oily liquid. The gas produced gives a pop sound with a lighted splinter, indicating the presence of hydrogen gas. The oily liquid obtained decolorizes bromine solution, indicating the presence of an unsaturated compound that can react with bromine. Therefore, the products of the cracking of medicinal paraffin are hydrogen gas and an unsaturated hydrocarbon (alkene), which is produced by breaking some of the carbon-carbon bonds in the original paraffin molecule.
Thus, the correct option is: hydrogen gas and alkene.
