Question

Compute the repeat unit molecular weight for nylon 6,6

 

**Poly(hexamethylene adipamide) (nylon 6,6)** - **Diagram Explanation:** - *Left Side:* A structural formula diagram showing a repeating unit of nylon 6,6. The structure features alternating blue and red atoms. Blue likely represents nitrogen (N) atoms, and red likely represents oxygen (O) atoms, integrated within a hexagonal arrangement. - *Right Side:* A detailed chemical structure of nylon 6,6 displayed as a repeating segment of the polymer chain. This includes: - A blue nitrogen (N) atom bonded to a carbon (C) atom. - The carbon atoms (C) are bonded to hydrogen (H) atoms. - Oxygen (O) atoms are double-bonded to some of the carbon atoms, indicating carbonyl (C=O) groups. - The molecular structure repeats along a linear chain, showing the backbone of the nylon polymer formed from amide linkages between the hexamethylene and adipic acid segments. Nylon 6,6 is a synthetic polymer formed through the polycondensation of hexamethylene diamine and adipic acid, resulting in strong and flexible fibers widely used in textiles and industrial applications.
