Question

What are the intermolecular forces in acrilan?

(a) Hydrogen bonds

(b) Dipole-dipole interaction between carbonyl groups

(c) Dipole-dipole interaction between carbonyl and cyano groups

(d) Van der Waals forces

I got this question in class test.

The origin of the question is Classification of Polymers topic in division Polymers of Chemistry – Class 12

Answer 1

Correct choice is (c) Dipole-dipole interaction between carbonyl and cyano groups

The best I can explain: Acrilan is a fibre of polyacrylonitrile. It forms strong intermolecular bonds through dipole-dipole interactions between the carbonyl and cyano groups.
