Explain the uniqueness of carbon, state five sources of organic compounds, and define homologous series with four characteristics.

Here are the solutions to your chemistry questions:

Question 1:

a) Explain the uniqueness of carbon in forming many organic compounds.
Carbon's uniqueness stems from its ability to form strong covalent bonds with other carbon atoms (catenation), leading to long chains, branched structures, and rings. It is also tetravalent, allowing it to form four bonds with other atoms, and can form single, double, and triple bonds, contributing to the vast diversity of organic compounds.

b) State five sources of organic compounds.

• Petroleum
• Natural gas
• Coal
• Plants (biomass)
• Animals (fats, proteins)

c) Alkanes constitute a homologous series of organic compounds. Define homologous series and state four characteristics of it.
