The above compound describes a condensation polymer which can be obtained in two ways: either treating 3 molecules of acetone (CH3COCH3) with conc. H2SO4 or passing propyne (CH3C≡CH) through a red hot tube. The polymer is

1. Phorone
2. Mesityl oxide
3. Deacetonly alcohol
4. Mesitylene

Correct answer: Mesitylene

Solution

The polymer described is mesitylene, which is formed by the condensation of three molecules of acetone in the presence of concentrated H2SO4 or by passing propyne through a red-hot tube.
