Statement (I) : Oxygen being the first member of group 16 exhibits only –2 oxidation state.

Question

Given below are two statements: 

Statement (I) : Oxygen being the first member of group 16 exhibits only –2 oxidation state. 

Statement (II) : Down the group 16 stability of +4 oxidation state decreases and +6 oxidation state increases. 

In the light of the above statements, choose the most appropriate answer from the options given below: 

(1) Statement I is correct but Statement II is incorrect 

(2) Both Statement I and Statement II are correct 

(3) Both Statement I and Statement II are incorrect 

(4) Statement I is incorrect but Statement II is correct

Answer 1

(3) Both Statement I and Statement II are incorrect 

Statement-I: Oxygen can have oxidation state from –2 to +2, so statement I is incorrect 

Statement- II: On moving down the group stability of +4 oxidation state increases whereas stability of +6 oxidation state decreases down the group, according to inert pair effect.

So both statements are wrong.
