Chemistry
1 answer:
oksian1 [2.3K]3 years ago
4 0

Answer:

1) 1-Pentyne

2) But-2-yne

3) Ethyne

4) 1-Propyne

5) 1-Butyne

6) Pent-2-yne

Explanation:

1) The number of carbon on the longest chain = 5, (two carbon atoms between the triple bond) therefore the prefix is <em>pen-</em>

The functional group is the triple bond on the first carbon with the suffix <em>-yne</em>

The name of the compound is 1-Pentyne

2) There are 4 carbon atoms on the longest chain, therefore, the prefix is <em>but-</em>

The location of the triple bond functional group (suffix; <em>-yne</em>) 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 <em>prop-</em>, and the functional group on the first carbon atom on the longest chain is the triple bond, with suffix <em>-yne</em>

Therefore, the name of the compound is 1-Propyne

5) The number of carbon atoms on the longest chain = 4, the prefix is <em>but-</em>

The location of the triple bond functional group (suffix<em> -yne</em>) 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 <em>pen-</em>

The location of the triple bond functional group (suffix; <em>-yne</em>) is on the second carbon atom, therefore;

The name of the compound is Pent-2-yne
