Polymers Class 12 Notes – Chapter 15 Polymers are derived from monomers which consist of repeating structural units of high molecular mass macromolecules. They may occur in natural or synthetic form and are classified in many ways such as based on origin, structure, etc. Please refer Polymers Class 12 Notes for more revision notes.

Biomolecules Class 12 Notes – Chapter 14 Biomolecules describe the molecules required by living things to build body parts and maintain the biochemical processes required for life functions. These biomolecules may be classed as either organic or inorganic compounds. Organic compounds are compounds containing carbon that are found in living things. Please refer Biomolecules Class 12 Notes for …
