Chapter 9: Problem 33

The commercial name of polyacrylonitrile is (A) Dacron (B) Orlon (acrolin) (C) \(\mathrm{PVC}\) (D) Bakelite

Short Answer

Expert verified
The commercial name of polyacrylonitrile is (B) Orlon (acrolin), as it has the same chemical structure \(\mathrm{[-CH_2-CH(CN)-]_n}\).

Step by step solution

01

Identify the chemical structure of polyacrylonitrile

Polyacrylonitrile is a synthetic polymer composed of repeating units of acrylonitrile, which has the chemical formula \(\mathrm{C_3H_3N}\). Its structure can be written as \( \mathrm{[-CH_2-CH(CN)-]_n} \)
02

Compare with the given options

We can now compare polyacrylonitrile's structure with the structures of the materials given in the options: (A) Dacron: Dacron is a commercial name for polyethylene terephthalate (PET) which has a different chemical structure than polyacrylonitrile. (B) Orlon (acrolin): Orlon is a commercial name for polyacrylonitrile. It has the same chemical structure as polyacrylonitrile. (C) \(\mathrm{PVC}\): \(\mathrm{PVC}\) is an abbreviation for polyvinyl chloride which has a different chemical structure than polyacrylonitrile. (D) Bakelite: Bakelite is a phenol-formaldehyde resin that has a different chemical structure than polyacrylonitrile.
03

Choose the correct answer

Since Orlon (acrolin) has the same chemical structure as polyacrylonitrile, the correct answer is: (B) Orlon (acrolin)
