Which of the following monomeric pair is used to make polymer Nylon 6, 6?

Hexane -1,6-dioic acid and Hexane -1,6-diamine

The correct answer is option 1. Hexane -1,6-dioic acid and Hexane -1,6-diamine.

Nylon 6, 6 is a type of polyamide (nylon) that is synthesized by the condensation polymerization of hexane-1,6-dioic acid (adipic acid) and hexane-1,6-diamine. This process involves the reaction between the carboxylic acid group of adipic acid and the amino group of hexane-1,6-diamine, forming amide linkages and producing the polymer with repeating units.
