Question

Benzene is a polymer of a)ethylene b)acetylene c)isoprene d)ethyne ..GIVE SMALL REASON IN SUPPORT OF UR SELECTIVE OPTION

Answer 1

Acetylene

when acetylene on passing through red hot tube in presence of organo nickel catalyst forms benzene by polymerization.


3 C2H2 ---------- C6H6

Answer 2

Answer: Option (d) is the correct answer.

Explanation:

A polymer is defined as a substance that consists of number of monomer units which are joined together.

For example, at 873 K through a red hot iron tube acetylene is passed and molecules of acetylene combine together through chain polymerization to result into the formation of benzene.

         $3C_{2}H_{2} \overset{red hot irn tube}{\rightarrow} C_{6}H_{6}$
