Question
Consider the empirical chemical formula of the repeating unit of the polymer Nylon-6,6. What is the total number of carbon atoms present in exactly one repeating unit?
Answer: 12
💡 Solution & Explanation
The repeating unit of Nylon-6,6 is $[-NH-(CH_2)_6-NH-CO-(CH_2)_4-CO-]$. The hexamethylenediamine portion contributes 6 carbon atoms, and the adipic acid portion contributes 6 carbon atoms ($1+4+1$). Total carbon atoms = $6 + 6 = 12$.
