The nature of oxide (TeO2) and hydride (TeH2) formed by Te, respectively are:

1. Reducing and basic
2. Reducing and acidic
3. Oxidising and acidic
4. Oxidising and basic

A group 15 element forms d - d bond with transition metals. It also forms a hydride, which is the strongest base among the hydrides of other group members that form d - d bond. The atomic number of the element is .

The large difference between the melting and boiling points of oxygen and sulphur may be explained on the basis of

1. Atomicity
2. Electron gain enthalpy
3. Atomic size
4. Electronegativity

The incorrect statement among the following is

1. PH3 shows lower proton affinity than NH3.
2. SO2 can act as an oxidizing agent, but not as a reducing agent.
3. NO2 can dimerise easily.
4. PF3 exists but NF5 does not.
