Identify FALSE statement from following.

Options

  1. ABoiling point of sulfur is lower than oxygen.
  2. BIonization enthalpy of group 16 elements gradually decreases from top to bottom.
  3. CGroup 16 elements have lower ionization enthalpy than group 15 elements in corresponding periods.
  4. DOxygen has highest electronegativity next to fluorine amongst all the elements.

Correct answer

A. Boiling point of sulfur is lower than oxygen.

Step-by-step solution

Melting and boiling points of elements of group 16 increase with increasing atomic number. Therefore, oxygen has low melting and boiling points as compared to sulfur.
