Introduction:

When hydrogen atoms are replaced by a functional group, the hydrocarbon is called substituted hydrocarbon.

Ethanoic acid $\left({\text{CH}}_{\text{3}}\text{COOH}\right)$ - This is a substituted hydrocarbon. One hydrogen atom has been replaced by COOH.

Ethanol $\left({\text{C}}_2{\text{H}}_5\text{OH}\right)$ - This is a substituted hydrocarbon. One hydrogen atom has been replaced by OH.

Tetrachloroethene $\left({\text{C}}_2{\text{Cl}}_4\right)$ - This is a substituted hydrocarbon. One hydrogen atom has been replaced by ${\text{Cl}}_4$ .

Conclusion:

All compounds are substituted hydrocarbons.
