Question

The starting material for the preparation of styrene is:
A. Ethane
B. Ethene
C. Ethyne
D. Vinyl chloride

Answer 1

Hint: Polymer is generally a combination of two words known as poly and mer where poly means many and mer refers with parts i.e. many parts as polymers are made up with repeating units of monomers where monomer is a single part of any unit.

Complete answer:
Monomer is made up of two words mono + mer were mono means single and mer means part, hence monomer is known as single part and monomer combine with each other to form long chain polymers or three dimensional compounds and this process is known as polymerization.
Polymers are formed by the process of polymerization. It is the process in which small monomers are joined together through the process of addition polymerization and there are many industrial and other uses of polymers.
Styrene is also known by the name ethylbenzene this can be represented by the chemical formula \[{{C}_{6}}{{H}_{5}}-CH=C{{H}_{2}}\], so the starting material from which it is prepared is ethylene which reacts with benzene and form styrene. Ethylene also known by the name ethene is kept in the category of alkene where alkene are those compounds which contain double bond in them and can be represented by the chemical formula \[C{{H}_{2}}=C{{H}_{2}}\].

Hence option B is the correct answer.

Note:
Polymers are of two types named as natural polymers and synthetic polymers. Natural polymers are those which we obtained from nature i.e. from plants and animals whereas synthetic polymers are also known as artificial or man-made polymers i.e. those polymers which are prepared synthetically in lab by man.
