What is the correct name of the compound that is incorrectly named 1-chloro-3-pentyne?

Answered by maham237 @



Answer:

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.
