Question

Which series is the most reactive series?
alkyne
alkene
alkane
methane

Answer 1

alkyne

Step-by-step explanation:

An alkyne is a hydrocarbon in which at least one pair of carbon atoms is bound with a triple bond. A triple bond takes more energy to maintain in the molecule and as such is less stable than a single or double bond. Thus, an alkyne is more likely to react with less activation energy than that of an alkane or an alkene.

Answer 2

Hello.

Alkali metals are the most reactive group in the periodic table, not to be confused with Alkaline earth metals.

Also, Methane is a gas, not a group on the periodic table.

they contain triple bond, one sigma bond and 2 pi bonds. Pi bonds are weak and easily broken making the compound active.

Chemical reaction is the process of breaking down bonds in reactants and forming new bonds in products.
In Alkynes breaking down bonds is easier so they are more active.


Have a nice day
