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 lowest value which can be assigned to $\mathrm{n}$.

Answer 1

1. The organic compounds consisting of Carbon $\left(\mathrm{C}\right)$ and Hydrogen $\left(\mathrm{H}\right)$ atoms 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 and 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 lowest value can be assigned to $\left(\mathrm{n}\right)$ is $2$ that forms Ethene having the formula is $\left({\mathrm{C}}_2{\mathrm{H}}_4\right)$.
