Question

Oxygen generally exhibits an Oxidation state of -2 while the other members of the group show Oxidation State of + 2 + 4 and + 6 also – explain.

Answer 1

Hint: Oxygen is very electronegative and can take up electrons promptly to finish its valence shell and show an Oxidation state of – 2. Oxygen additionally shows an Oxidation state of +1 and +2 in mixes of oxygen with fluorine.
In fact, + 2 Oxidation state is accomplished distinctly with exceptionally oxidizing components like fluorine.

Complete answer:
Oxygen cannot extend its valence past two because of absence of “d” orbital in its valence shell. This discloses with regards to why oxygen can’t show an Oxidation state of +4, +6.
Every single other component of the gathering has an empty d orbital in their valence shell and subsequently can expand their valence past two and can show an Oxidation state of +4, +6.
It’s relevant to specify that lower Oxidation state attributable to “idle pair impact” thus an Oxidation state of +6 is phenomenal in heavier individuals from the group. Oxygen does not show +4, +6 and likewise +2 once in a while (for the most part in the compound of2, oxygen difluoride) due to progressively electronegative components in the occasional table after fluorine (this is clarification as I probably am aware oxygen doesn’t show +4, +6 oxidation state).
In the event that outcomes from the test that oxygen additionally show +4, +6 oxidation state, at that point, we clarify it.

These are from 16 gatherings, and they have 6 valence electrons and additionally bunch 16 part shows +6 electrons or on the other hand some other clarification.
Along these lines, we presume that each component is individual, albeit numerous properties are comparable in an intermittent table.

Note: In any case, those properties which are not comparable or component shows anomalous conduct from their group then we tell it as an exception. In this way, basically, you need to learn that oxygen does not show +4, +6 and sulfur, and another component shows +4, +6 oxidation state.
