Q: Which of the following is the correct name for CH3-CH2-NH2?

Solution: The compound is an amine with two carbon atoms, and the correct IUPAC name is ethanamine.

Steps: 6

Step 1: Identify the structure of the compound CH3-CH2-NH2. It has two carbon atoms (CH3 and CH2) and an amine group (NH2).
Step 2: Count the number of carbon atoms. There are 2 carbon atoms in total.
Step 3: Determine the longest carbon chain. The longest chain here is 2 carbon atoms long.
Step 4: Name the carbon chain. A 2-carbon chain is called 'ethane'.
Step 5: Since there is an amine group (NH2) attached to the carbon chain, we change 'ethane' to 'ethanamine'.
Step 6: Conclude that the correct IUPAC name for CH3-CH2-NH2 is ethanamine.
