Question

How is propene the second member of the alkene series?
Is it not ethene?

Answer 1

Answer:

Explanation:

The alkene series cannot start with a single Carbon atom (-C=) . So meth-ene formation isn't possible. The next member Ethene is the first member of the series as it fulfil the requirement of atleast 2 carbon atoms (-C=C-)

Hence, the 3Carbon alkene molecule(Propene) is second member of the alkene homologous series
