Electrophilic Addition in Alkynes
Reactions involving alkynes often follow the mechanism of electrophilic addition. This is because alkynes are highly reactive due to the presence of two pi bonds, which can easily break to form new bonds with electrophiles.
Key Points:
- In electrophilic addition, an electrophile attacks the pi bond in the alkyne, leading to the formation of new sigma bonds.
- This results in the addition of atoms or groups to the carbon atoms of the alkyne.
- The addition can take place in a stepwise manner, with the formation of an intermediate carbocation.
- Common electrophilic additions to alkynes include hydration, halogenation, and hydrogenation reactions.
Example:
One common example of electrophilic addition in alkynes is the hydrogenation of an alkyne to form an alkane. In this reaction, hydrogen gas (H2) reacts with the alkyne in the presence of a metal catalyst to produce an alkane.
Therefore, the majority of reactions of alkynes are examples of electrophilic addition, where electrophiles add to the carbon-carbon pi bond in the alkyne, leading to the formation of new sigma bonds and the addition of atoms or groups to the molecule.
