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.

Answer: The correct answer is alkyne.

Step-by-step explanation:

All the given compounds are a type of hydrocarbons because a covalent bond is present between hydrogen and carbon atoms.

Alkane are the series of compounds where a single bond is present between carbon and carbon atoms.

Alkenes are the series of compounds where double bond is present between carbon and carbon atoms.

Alkynes are the series of compounds where double bond is present between carbon and carbon atoms.

Alkenes are Alkynes are considered as unsaturated compound and these undergo addition reaction the most because of the presence of pi-bonds between carbon-carbon atoms.

The reactivity of the series undergoing addition reaction is:


\text{Alkynes}>\text{Alkenes}>\text{Alkanes}

Alkynes have 2 pi-bonds, alkenes have 1 pi-bond and alkanes have 0 pi-bonds.

Hence, the correct answer is alkyne.
