Question

Addition reaction and substitution reaction is a type of organic reaction, which type of reaction is shown by Ethane.

Answer 1

1. A reaction in which one atom or a group of atoms of a molecule is replaced by another atom (or group of atoms) is called a substitution reaction.
2. Alkanes (saturated hydrocarbons) undergo substitution reactions with Halogen in the presence of sunlight.
3. Example: Ethane $({\mathrm{C}}_2{\mathrm{H}}_6)$ is a saturated hydrocarbon, therefore, it undergoes a substitution reaction to form Alkyl halide.
4. The reaction is as follows:

$\underset{\mathrm{Ethane}}{{\mathrm{C}}_2{\mathrm{H}}_6\left(\mathrm{g}\right)}+\underset{\mathrm{Bromine}}{{\mathrm{Br}}_2\left(\mathrm{l}\right)}\to \underset{\mathrm{Bromoethane}}{{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{Br}\left(\mathrm{l}\right)}+\underset{\mathrm{Hydrogen}\mathrm{bromide}}{\mathrm{HBr}\left(\mathrm{g}\right)}$

If the organic compound contains a double or triple bond then only they can undergoes addition reaction.
