Question:
The monomer involved in the formation of polystyrene is
The monomer involved in the formation of polystyrene is
Show Hint
Polystyrene is formed from styrene, whose structure is \(CH_2=CH-C_6H_5\).
Updated On: May 7, 2026
- \(CH_2=CH-Cl\)
- \(CH_2=CH-CN\)
- \(CH_2=CH-C_6H_5\)
- \(CH_2=CH-CH_3\)
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Polystyrene is an addition polymer.
Step 2: The monomer of polystyrene is styrene.
Step 3: Structure of styrene is: \[ CH_2=CH-C_6H_5 \]
Step 4: During polymerization, the double bond opens and many styrene units join together. \[ n(CH_2=CH-C_6H_5)\rightarrow [-CH_2-CH(C_6H_5)-]_n \]
Step 5: Hence, the monomer of polystyrene is: \[ \boxed{CH_2=CH-C_6H_5} \]
