Question

1. match the branch of chemistry with the correct example: branch example answer organic chemistry a. dna and proteins ____ inorganic chemistry b. plastics and fuels __ biochemistry c. iron and table salt ____

Explanation:

• Organic Chemistry deals with carbon - containing compounds. Plastics (polymers with carbon backbones) and fuels (like hydrocarbons) are organic compounds, so Organic Chemistry matches with B.
• Inorganic Chemistry deals with non - carbon - based (or less carbon - centered) compounds. Iron (a metal) and table salt (NaCl, an ionic compound) are inorganic, so Inorganic Chemistry matches with C.
• Biochemistry deals with chemical processes in living organisms. DNA and proteins are essential biomolecules, so Biochemistry matches with A.

Answer:

Organic Chemistry: B. Plastics and fuels
Inorganic Chemistry: C. Iron and table salt
Biochemistry: A. DNA and proteins
