Given below are two statements : In the light of the above statements, choose the correct answer from the options given below :
- Statement I is true but Statement II is false
- Both Statement I and Statement II are false
- Both Statement I and Statement II are true
- Statement I is false but Statement II is true
Answer
(3) Both Statement I and Statement II are true
Solution
Statement I: in d-block, higher oxidation states become more stable down a group (e.g. Mo(VI), W(VI) are more stable than Cr(VI)); in p-block the lower states become more stable (inert pair effect). So Statement I is true.
Statement II: E Cu2+/Cu = +0.34 V, i.e. Cu is below hydrogen in the electrochemical series, so it cannot reduce H+ to H2. So Statement II is true.
Answer: (3)
