What is the IUPAC name of the compound CH≡C-CH2-CH3?

Correct Answer: 1-butyne

Step 1: Identify the longest carbon chain in the compound. In CH≡C-CH2-CH3, the longest chain has 4 carbon atoms.
Step 2: Determine the type of bond present. The '≡' symbol indicates a triple bond between the first two carbon atoms.
Step 3: Number the carbon chain starting from the end closest to the triple bond. This gives us the following numbering: 1 (triple bond) - 2 - 3 - 4.
Step 4: Use the IUPAC naming conventions. Since there is a triple bond, we use the suffix '-yne'.
Step 5: Combine the number of the first carbon with the suffix. The first carbon with the triple bond is at position 1, so we name it '1-butyne'.
