Given below are two statements: Statement (I) : Oxygen being the...
Statement (I) : Oxygen being the first member of group exhibits only oxidation state.
Statement (II) : Down the group stability of oxidation state decreases and oxidation state increases.
In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- AStatement I is correct but Statement II is incorrect
- BBoth Statement I and Statement II are correct
- CBoth Statement I and Statement II are incorrect
- DStatement I is incorrect but Statement II is correct
Correct answer
C. Both Statement I and Statement II are incorrect
Step-by-step solution
Statement-I: Oxygen can have oxidation state from to , so statement I is incorrect
Statement- II: On moving down the group stability of oxidation state increases whereas stability of oxidation state decreases down the group, according to inert pair effect.
The inert-pair effect is the tendency of the two electrons in the outermost atomic s-orbital to remain unshared in compounds of post-transition metals.
So both statements are wrong.
