Questions & Step-by-Step Solutions

What is the IUPAC name of CH3CH2Cl?
  • Step 1: Identify the longest carbon chain in the molecule. CH3CH2Cl has two carbon atoms, so the longest chain is two carbons long.
  • Step 2: Name the longest carbon chain. A two-carbon alkane is called 'ethane'.
  • Step 3: Identify the substituent. The molecule has a chlorine atom (Cl) attached to one of the carbon atoms.
  • Step 4: Combine the names. Since there is a chlorine substituent, we add 'chloro' before the name of the alkane.
  • Step 5: Write the full name. The full IUPAC name is 'Chloroethane'.
