Answer from: brittanysanders

The correct name is 5-chloro-2-pentyne.

Explanation:

Kindly see the attached image.It summarizes the rules of IUPAC system to name the compounds.We have 5 carbon atoms that take the name (pent).The carbon skeleton should be numbered that the position of the triple bond should have the lowest number in the skeleton, so the triple bond is between C2 and C3.It takes the lowest number (2) and added (yne) at the end of the name.(yne) is express the presence of triple bond.The (Cl) atom take the number 5.So, the correct name of the compound is 5-chloro-2-pentyne.

Answer from: jaeybird9

5-chloro 2 pentyne is the correct name of the compound that is incorrectly named 1-chloro-3-pentyne

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

Further explanation

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 it2. Naming the triple bond from the main chain based on the location of the C atom which has a triple bond3. Numbering starting from C atoms which have triple bonds gets the smallest value4. 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

¹ ² ³ ⁴ ⁵
