Questions & Step-by-Step Solutions

What is the IUPAC name for the compound with the formula C5H10?
  • Step 1: Identify the molecular formula C5H10. Count the number of carbon (C) and hydrogen (H) atoms.
  • Step 2: Determine the degree of saturation. Since C5H10 has fewer hydrogens than C5H12 (which is a saturated alkane), it indicates that there is a double bond.
  • Step 3: Recognize that compounds with a double bond are called alkenes.
  • Step 4: Count the number of carbon atoms. There are 5 carbon atoms, which means the base name will be 'pent' (for 5 carbons).
  • Step 5: Since it is an alkene, the name will be 'pentene'.
  • Step 6: Note that without specifying the position of the double bond, the compound is simply referred to as pentene.
