Question

When identifying the monomeric unit of a commercial polymer, consider the structure of Polystyrene. What is the total number of $sp^2$ hybridized carbon atoms in a single molecule of the unreacted styrene monomer?

Answer: C

💡 Solution & Explanation

Styrene is vinylbenzene ($C_6H_5-CH=CH_2$). The aromatic benzene ring contains 6 $sp^2$ carbons, and the vinyl group contains 2 $sp^2$ carbons connected by a double bond. Total $sp^2$ carbons = $6 + 2 = 8$.
