Question

The molecules of the alkene family are represented by the genral formula ${\mathrm{C}}_{\mathrm{n}}{\mathrm{H}}_{2\mathrm{n}}$. What is the molecular formula of alkene when the value of $\mathrm{n}$is $4$

Answer 1

1. Hydrocarbons are made up of Carbon $\left(\mathrm{C}\right)$ and Hydrogen $\left(\mathrm{H}\right)$ atoms connected with single or multiple bonds are known as hydrocarbons.
2. Hydrocarbons are of two types depending on the kind of bonds formed between Carbon-Carbon atoms, saturated hydrocarbons, and unsaturated hydrocarbons
3. The organic compounds containing Carbon atoms having triple or double bonds between two Carbon atoms are called unsaturated hydrocarbons.
4. Alkenes contain double bonds between the Carbon atoms so it is an unsaturated hydrocarbon.
5. The molecules of the alkene family are represented by the general formula $\left({\mathrm{C}}_{\mathrm{n}}{\mathrm{H}}_{2\mathrm{n}}\right)$.
6. The number of Carbon atoms is represented by $\left(\mathrm{n}\right)$ and $\left(2\mathrm{n}\right)$ represents the number of Hydrogen atoms in a molecule of alkene.
7. The structural formula of Butene is $({\mathrm{CH}}_3-\mathrm{CH}=\mathrm{CH}-{\mathrm{CH}}_3)$.
8. The molecular formula of alkene is Butene $\left({\mathrm{C}}_4{\mathrm{H}}_8\right)$ when the value of $\left(\mathrm{n}\right)$ is $4$.
