The incorrect statements among the following is (1) PH3 shows lower proton affinity than NH3. (2) PF5 exists but NF5 does not. (3) NO2 can dimerise easily. (4) SO2 can act as an oxidizing agent, but not as a reducing agent.

1. PH3 shows lower proton affinity than NH3.
2. PF5 exists but NF5 does not.
3. NO2 can dimerise easily.
4. SO2 can act as an oxidizing agent, but not as a reducing agent.

Correct answer: SO2 can act as an oxidizing agent, but not as a reducing agent.

Solution

SO2 can indeed act as an oxidizing agent due to its ability to accept electrons, but it can also act as a reducing agent under certain conditions, making the statement incorrect.
