46. The correct order of increasing boiling points of the compounds C7H16, C4H10 and C3H7OH is A. C7H16 -> C3H7OH -> C4H10 B. C4H10 -> C3H7OH -> C7H16 C. C3H7OH -> C4H10 -> C7H16 D. C4H10 -> C7H16 -> C3H7OH

  • A. C7H16 -> C3H7OH -> C4H10
  • B. C4H10 -> C3H7OH -> C7H16
  • C. C3H7OH -> C4H10 -> C7H16
  • D. C4H10 -> C7H16 -> C3H7OHCorrect

Explanation

C3H7OH has the highest boiling point because it has a polar (OH) group, which allows hydrogen bonding. C4H10 -> C7H16 -> C3H7OH is the correct order of increasing boiling points.
