Solution Steps

Step 1: Identify the molecular formula of each compound
  • Compound I: Cyclohexanone (C6H10O)
  • Compound II: Pentanal (C5H10O)
  • Compound III: Cyclopentanol (C5H10O)
  • Compound IV: 2-Methyl-2-propanol (C4H10O)
Step 2: Compare the molecular formulas
  • Compound I: C6H10O
  • Compound II: C5H10O
  • Compound III: C5H10O
  • Compound IV: C4H10O
Step 3: Determine which compounds have the same molecular formula
  • Compounds II and III both have the molecular formula C5H10O.

Final Answer

Compounds II and III are constitutional isomers. Therefore, the correct answer is:

  • b and c
