Question

Which branch of chemistry primarily focuses on the study of carbon-containing compounds, and is essential for understanding the structure of medicines and plastics?

This question was previously asked in
RRB Technician 2026 Grade 3 Question Paper (7-Oct-2026) (Shift 3)
The correct answer is

Organic chemistry

Organic chemistry is the study of carbon compounds – hydrocarbons and their derivatives. Because carbon atoms can link with one another in long chains, branches and rings, they form a huge variety of compounds.

Most medicines (such as aspirin and paracetamol) and plastics (such as polythene and PVC) are carbon-based molecules or polymers, so understanding their structure and properties depends on organic chemistry.

Physical chemistry deals with energy changes, reaction rates and equilibrium; inorganic chemistry deals mainly with metals, minerals and non-carbon compounds; and analytical chemistry deals with identifying substances and finding their amounts. None of these is the branch centred on carbon compounds.

Hence, Organic chemistry.
