The melting point of oxygen is very low compared to that of sulphur because ______.

Options

  1. Aoxygen is composed of diatomic molecules while sulphur is polyatomic
  2. Bthe magnitude of Van der Waals forces in oxygen is higher than that of sulphur
  3. Coxygen is a stronger oxidizing agent than sulphur
  4. Doxygen is more electronegative than sulphur

Correct answer

A. oxygen is composed of diatomic molecules while sulphur is polyatomic

Step-by-step solution

In group 16 th element, the molecular mass of oxygen gas is very low as compared to sulphur atom because sulphur element is polyatomic and the oxygen element is diatomic. The melting point is directly proportional to the molecular mass of elements. So, sulphur has the highest melting point as compared to the oxygen elements.
