Question

At which temperature, does cyclic polymerization of an alkyne occur?

(a) 871 Kelvin

(b) 872 Kelvin

(c) 873 Kelvin

(d) 874 Kelvin

The question was asked in examination.

I need to ask this question from Hydrocarbons topic in section Hydrocarbons of Chemistry – Class 11

Answer 1

The correct option is (c) 873 Kelvin

To explain I would say: An example of cyclic polymerization of an alkyne is given by; when 3 moles of ethane is at 873 Kelvin in presence of red hot iron tube they polymerise in a cyclic form in order to form Benzene a six-membered ring with alternate double bonds.
