Answer 2

I) Decarboxylation is a chemical reaction that removes a carboxyl group and releases carbon dioxide (CO2). Usually, decarboxylation refers to a reaction of carboxylic acids, removing a carbon atom from a carbon chain.

ii) Ozonolysis is an organic reaction where the unsaturated bonds of alkenes, alkynes, or azo compounds are cleaved with ozone. Alkenes and alkynes form organic compounds in which the multiple carbon–carbon bond has been replaced by a carbonyl group while azo compounds form nitrosamines.

iii) In cyclic polymerization, alkyne molecules add to each other, resulting in the formation of a cyclic compound. Ex: When ethyne is passed through a red hot iron tube at 873K it undergoes cyclic polymerization. In cyclic polymerization, three molecules of ethyne polymerize to form benzene.
