Given below are two statements:Statement I: The boiling point of hydrides of Group 16 elements follows the order .Statement II: has the highest boiling point due to extensive hydrogen bonding.

  1. A
    Both Statement I and Statement II are false
  2. B
    Statement I is true but Statement II is false
  3. C
    Statement I is false but Statement II is true
  4. D
    Both Statement I and Statement II are true

Solution & Step-by-step Explanation

1. Usually, boiling points increase with molecular mass due to increasing Van der Waals forces. Order based on mass: .2. However, has exceptionally high boiling point because of strong intermolecular hydrogen bonding.The combined order is . Both statements are correct.
