WBJEE 2026 Physics and Chemistry Paper

Identify the correct statements about polymers and their monomers.Explanation:Option A: Starch is a polysaccharide made of repeating $\alpha$-D-glucose units. Hence, statement A is correct.Option B: Nylon 6 is a condensation polymer, not an addition polymer. Nylon 66 is also a condensation polymer. Hence, statement B is incorrect.Option C: Natural rubber is a polymer of isoprene ($\mathrm{C}_5\mathrm{H}_8$). Hence, statement C is correct.Option D: Bakelite is obtained from phenol and formaldehyde, not acetaldehyde. Hence, statement D is incorrect.Answer:The correct statements are A and C.
