Ozonolysis breaks pi bond and results in formation ketone. This is then undergoing aldol condensation to give 2-cyclopentenone.
It means it is a polymer formed by addition of isoprene units ,natural rubber and gutta parcha.It can also cis and trans isomers.

This seems like a bit of a complicated question. I have done some research but can not resolve the answer. It would be great if someone can answer it with a bit of explanation.
If you don't know what ozonolysis is?
Ozonolysis is a reaction used in organic chemistry to determine the position of a carbon-carbon double bond in unsaturated compounds. ... It is used in the synthesis of rare aldehydes and ketones and in the study of the structure of aromatic compounds.
