Question

Given below are two statements:

• A. Both Statement I and Statement II are correct
• B. Statement I is incorrect, Statement II is correct
• C. Statement I is correct, Statement II is incorrect
• D. Both Statement I and Statement II are incorrect

Answer 1

The Correct Option is A

Step 1: Understanding metamerism (Statement I).
Metamerism is a type of structural isomerism shown by compounds having the same molecular formula and functional group but different alkyl groups on either side of a polyvalent functional group (like \(-CO-\), \(-O-\), \(-NH-\)).
In ketones, metamerism arises due to different distribution of alkyl groups on either side of the carbonyl group. The given two ketone structures have the same molecular formula but differ in the arrangement of carbon chains around the \(>C=O\) group.
Hence, they are metamers. Therefore, Statement I is correct.
Step 2: Understanding tautomerism (Statement II).
Tautomerism (specifically keto-enol tautomerism) occurs in compounds having at least one \(\alpha\)-hydrogen atom (hydrogen on the carbon adjacent to the carbonyl group).
The given compound contains a carbonyl group and has \(\alpha\)-hydrogen atoms. These hydrogens can shift along with the movement of electrons, resulting in equilibrium between keto and enol forms.
Thus, the compound will show tautomerism. Hence, Statement II is also correct.
Step 3: Verification of both statements.

• Statement I: Correct (metamerism present in ketones)
  
• Statement II: Correct (presence of \(\alpha\)-hydrogen enables tautomerism)
  

Step 4: Conclusion.
Both Statement I and Statement II are correct.
Final Answer:} (A)
