<\/figure>\n\n\n\nTop 5 Polymers Questions (Important PYQs with Tricks)<\/h2>\n\n\n\n
Question 1: Addition vs Condensation Polymer<\/h3>\n\n\n\n
B. Terylene
C. PVC
D. Bakelite<\/p>\n\n\n\n
PVC (Polyvinyl chloride) is formed by addition polymerization of vinyl chloride monomers. Nylon-6,6 and Terylene are condensation polymers. This is a very common question in the Top 5 Polymers Questions<\/strong>.<\/p>\n\n\n\n
If small molecules like water or HCl are eliminated \u2192 condensation polymer. If not \u2192 addition polymer.<\/p>\n\n\n\n
\n\n\n\nQuestion 2: Natural vs Synthetic Polymer<\/h3>\n\n\n\n
B. Rubber
C. Teflon
D. PVC<\/p>\n\n\n\n
Natural rubber is obtained from latex of rubber trees. Nylon, Teflon, and PVC are synthetic polymers. This is a direct NCERT-based concept in Top 5 Polymers Questions<\/strong>.<\/p>\n\n\n\n
