SO,sulfur trioxygen Exceptions to the naming rules: Some compounds have accepted names H2O water NHs-- ammonia- o, ozone -nitrousoxide__ also known as-laughing gas CH methane

Explanation / Answer

1. we have to mention number of chlorines(di) in the name and only one oxygen is there (mono)

The correct name is dichloride monoxide

2. It is Phosphorous, not Potassium

The correct name is Phosphorous pentafluoride

3. It is Sulphur, not Silicon. Oxygen is also not mentioned.

The correct name is Sulphur dioxide

4. We have to spell oxygen as oxide in oxide

The correct name is Sulphur trioxide

The correct name is Sulphur dioxide
