1) I will never consider a cycloalkane an alkene since they have
very different chemical reactions but a cyclobutane is very strain
and does break easily and react. Unless all the other choices in
the question don't even have the alkene general formula, i will
never take that as the answer.
2) It is consider an additional reaction since each molecule is
added together to form a chain by the breaking of the double bond,
there is no additional product formed through this reaction.
May I ask, is the second question considered as addition
polymerisation? Thank you.
