Chemical Bonding and Molecular Structure question

2024 · Q103

NEETChemistryChemical Bonding and Molecular StructureMCQ+4 / −1

Given below are two statements:

Statement I: The boiling point of hydrides of Group 16 elements follow the order H2O>H2Te>H2Se>H2S. \mathrm{H}_2 \mathrm{O}>\mathrm{H}_2 \mathrm{Te}>\mathrm{H}_2 \mathrm{Se}>\mathrm{H}_2 \mathrm{S} \text {. }H2​O>H2​Te>H2​Se>H2​S. 

Statement II: On the basis of molecular mass, H2O\mathrm{H}_2 \mathrm{O}H2​O is expected to have lower boiling point than the other members of the group but due to the presence of extensive H\mathrm{H}H-bonding in H2O\mathrm{H}_2 \mathrm{O}H2​O, it has higher boiling point.

In the light of the above statements, choose the correct answer from the options given below:

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