Alkynes are hydrocarbons with carbon-carbon triple bonds in them. The simplest alkyne can be prepared by the process shown in Reaction 1.
Also consider the following reactions.
Quinoline is a heterocyclic amine.
The hybrid orbital that characterizes and differentiates alkynes from other simple hydrocarbons like alkanes and alkenes, is that alkynes have hybrid orbitals which have:
|A||75% p character and 25% s character|
|B||66% p character and 33% s character|
|C||50% p character and 50% s character|
|D|| None of the above|
