The formula of acrylonitrile is:
Correct answer: A. CH2=CH―CN
- A. CH2=CH―CN
- B. CH3―CH2―CH2―CN
- C. CH3―CH2―CN
- D. CH3―CN
Explanation
Explanation:This is the formula of acrylonitrile, which is an organic compound used in the production of synthetic fibers and resins. This option is not correct. This is the formula for propionitrile, which is another organic compound with a slightly longer carbon chain than acrylonitrile.This option is also incorrect. This is the formula for ethyl cyanide, which is a different organic compound with a longer carbon chain and a different functional group than acrylonitrile.This option is also incorrect. This is the formula for acetonitrile, which is yet another organic compound with a different carbon chain and different functional group than acrylonitrile.

About Polymers
Polymers are large molecules made from repeating monomer units joined by covalent bonds. The topic distinguishes addition polymers such as polyethylene, PVC and polystyrene from condensation polymers such as nylon and polyester, and relates chain structure to thermoplastics, thermosetting polymers, elastomers, properties, uses and environmental concerns.
