Answer 2

Alkenes contain at least one double bond. In the question it's given that we have to find an 3 carbon alkene which contains two double bonds.

Answer 3

This will be the basic structure of the compound. Now all we have to do is complete the valencies of the carbon by adding singly bonded to each carbon atoms.
