Question

The monomer used to produce orlon is:
(A) \[C{{H}_{2}}=CHF\]
(B) \[C{{H}_{2}}=CC{{l}_{2}}\]
(C) \[C{{H}_{2}}=CHCl\]
(D) \[C{{H}_{2}}=CHCN\]

Answer 1

Hint:
Orlon is also known as polyacrylonitrile. As the name contains a nitrile term it suggests that N is present in the monomer. According to this we can directly conclude D as a correct answer.

Complete step by step answer:
> Monomers are small molecules, mostly organic, that can join with other similar molecules to form very large molecules, or polymers. All monomers have the capacity to form chemical bonds to at least two other monomer molecules.
> Polymers are a class of synthetic substances composed of multiples of simpler units called monomers. Polymers are chains with an unspecified number of monomeric units.
> Orlon is a polyacrylonitrile. It is an additional polymer. The addition of polymerisation of acrylonitrile in presence of a peroxide catalyst leads to the formation of polyacrylonitrile.



Polyacrylonitrile is used as a substitute for wool in making commercial fibres as orlon or acrilan.
Hence, the monomer used to produce orlon is Acrylonitrile (vinyl cyanide) $C{{H}_{2}}=CHCN$.

So, the correct option is (D).

Note:
Monomers are small molecules that can join with other similar molecules to form very large molecules, or polymers. Remember, Orlon is known as Polyacrylonitrile(PAN).
