<h3>What is alkyne?</h3>
Molecules that contain a triple bond between two carbon atoms are known as alkynes.
1) The number of carbon on the longest chain = 5, (two carbon atoms between the triple bond) therefore the prefix is pen-
The functional group is the triple bond on the first carbon with the suffix -yne
The name of the compound is 1-Pentyne
2) There are 4 carbon atoms on the longest chain, therefore, the prefix is but-
The location of the triple bond functional group (suffix; -yne) is on the second carbon atom
Therefore, the name of the compound is But-2-yne
3) The triple bond functional group is between the only two carbon atoms, therefore, the name is Ethyne
4) The number of carbon atoms = 3, with a prefix prop-, and the functional group on the first carbon atom on the longest chain is the triple bond, with suffix -yne
Therefore, the name of the compound is 1-Propyne
5) The number of carbon atoms on the longest chain = 4, the prefix is but-
The location of the triple bond functional group (suffix -yne) is on the first carbon atom
Therefore, the name is 1-Butyne
6) The number of carbon atoms on the longest chain = 5, the prefix of the compound is pen-
The location of the triple bond functional group (suffix; -yne) is on the second carbon atom, therefore;
The name of the compound is Pent-2-yne
