Which of the following is the correct IUPAC name for the compound CH3-CH2-CH(CH3

Which of the following is the correct IUPAC name for the compound CH3-CH2-CH(CH3)-C≡C-H?

Which of the following is the correct IUPAC name for the compound CH3-CH2-CH(CH3)-C≡C-H?

Step 1: Identify the longest carbon chain in the compound. Count the number of carbon atoms in the chain.
Step 2: Look for any branches or substituents attached to the main chain. In this case, there is a methyl group (CH3) attached to the third carbon.
Step 3: Determine the type of bond present in the compound. Since there is a triple bond (C≡C), it is classified as an alkyne.
Step 4: Number the carbon atoms in the longest chain starting from the end closest to the triple bond. This helps in naming the compound correctly.
Step 5: Combine the information: The longest chain has 5 carbons (pentyne), and the methyl group is on the third carbon, making it 3-Methyl-1-pentyne.
