Which of the following statements is false about oxygen and sulphur?
Options
- AAtoms of oxygen and sulphur consist two unpaired electrons in valence shell.
- BOxygen and sulphur show -2,+4 and +6 oxidation states.
- COxygen is gas while sulphur is solid at room temperature.
- DHydride of oxygen is more stable than hydride of sulphur.
Correct answer
B. Oxygen and sulphur show -2,+4 and +6 oxidation states.
Step-by-step solution
To identify the false statement, each option is evaluated against the chemical properties of oxygen and sulphur. A) Both oxygen ( [ He ] 2s^2 2p^4 ) and sulphur ( [ Ne ] 3s^2 3p^4 ) possess two unpaired electrons in their valence p-orbitals. This statement is true. B) Oxygen rarely exhibits oxidation states beyond +2 due to high electronegativity and lack of d-orbitals, whereas sulphur commonly shows +4 and +6 states. Oxygen does not demonstrate +4 or +6 oxidation states, making this statement false. C) At room tem
