Question:medium

What are the compounds used to obtain nylon salt?

Show Hint

Nylon-6,6 gets its name because both of its starting monomers (Adipic acid and Hexamethylenediamine) contain exactly 6 carbon atoms each!
Updated On: Jun 19, 2026
  • Adipic acid and ammonia
  • Terephthalic acid and hexamethylenediamine
  • Adipic acid and hexamethylenediamine
  • $\beta$-hydroxybutyric acid and hexamethylenediamine
Show Solution

The Correct Option is C

Solution and Explanation

Step 1: Understanding the Concept:
Nylon-6,6 is made via a two-stage process. First, an acid-base neutralization occurs to form a "Nylon salt," which is then polymerized.

Step 2: Formula Application:
The monomers are Hexamethylenediamine (a base) and Adipic acid (an acid).

Step 3: Explanation:
When these two are mixed in equimolar proportions in methanol, they form a 1:1 salt called hexamethylenediammonium adipate. This salt is then heated under high pressure to remove water and form the polymer.

Step 4: Final Answer:
Adipic acid and hexamethylenediamine are used.
