  • question_answer
    Dioxygen is a gas but sulphur is a solid because

    A) oxygen atom has the tendency to form multiple \[p\pi -p\pi \] bonds

    B) S - S bond is not as stable as S = S bond

    C) O - O chains are less stable than S - S chains

    D) oxygen is paramagnetic while sulphur is diamagnetic.

    Correct Answer: A

    Solution :

    Oxygen atom can form multiple \[p\pi -p\pi \] bonds with other oxygen atom on account of small size while S=S is not so stable as compared to -S-S-S- chains. Hence S exists as S8 while O exists as \[{{O}_{2}}\].
