<em>5-chloro 2 pentyne is the correct name of the compound that is incorrectly named 1-chloro-3-pentyne</em>
Whereas the triple C atom should get the smallest number, so the triple C name should start from the left, to be: 5-chloro 2 pentyne
<h3><em>Further explanation</em></h3>
The rules for alkyne naming compounds are almost the same as alkanes, namely:
- 1. The longest chain is the chain that has the most C atoms that have a double bond in it
- 2. Naming the triple bond from the main chain based on the location of the C atom which has a triple bond
- 3. Numbering starting from C atoms which have triple bonds gets the smallest value
- 4. Branch chains are named according to the number of Coms with the name alkyl
Alkyne's general formula is CnH2n-2
It is known that the problem is 1-chloro-3-pentyne, then the structure is
CH₃ CH₂ ≡ CH₂ CH₂ CH-Cl
⁵ ⁴ ³ ² ¹
From the description according to the above formula, it shows that the triple C number is obtained from right to left, whereas the triple C atom should get the smallest number, so the triple C name should start from the left, to be: 5-chloro 2 pentyne
CH₃ CH₂ ≡ CH₂ CH₂ CH-Cl
