A saturated hydrocarbon has the formula ${\mathrm{C}}_{\mathrm{n}}{\mathrm{H}}_{12}$. The value of 'n' in this compound is.

• A saturated hydrocarbon is one with all carbon-carbon bonds that are single bonds. 
• A hydrocarbon is an organic compound made up of only carbon and hydrogen. Saturated hydrocarbons are hydrocarbons in which all of the carbon atoms are bonded to four other atoms, implying that no carbon-carbon multiple bonds exist in these organic compounds.

 $$\begin{gathered} \mathrm{Alkanes}={\mathrm{C}}_{\mathrm{n}}{\mathrm{H}}_{2\mathrm{n}+2} \\ 2\mathrm{n}+2=12 \\ 2\mathrm{n} = 10 \\ 2\mathrm{n} = 10 \\ \mathrm{n} = 5 \end{gathered}$$

Therefore, the correct option (B) 5.
