Alkynes readily undergo addition reactions with which of the following?
A
Water (H2O)
B
Oxygen gas (O2)
C
Hydrogen gas (H2)
D
Chlorine gas (Cl2)
correct option: c
In the presence of a suitable catalyst, alkynes can undergo hydrogenation reactions, where hydrogen atoms are added across the carbon-carbon triple bond, resulting in the formation of alkanes.
The reaction is represented as:
\[ \text{Alkyne} + \text{H}_2 \text{ (in the presence of a catalyst)} \rightarrow \text{Alkane} \]
Therefore, the correct answer is:
Hydrogen gas (H₂)
