Question

Given below are two statements: Statement (I):

are isomeric compounds.
Statement (II):

are functional group isomers.
In the light of the above statements, choose the correct answer from the options given below:

• A. Both Statement I and Statement II are true
• B. Statement I is false but Statement II is true
• C. Statement I is true but Statement II is false
• D. Both Statement I and Statement II are false

Hint:

Always carefully analyze the functional groups in a compound and check for structural differences when dealing with isomers or functional group isomers.

Answer 1

The Correct Option is D

To validate the claims made about the isomeric compounds, a detailed examination is performed:

Statement (I): Asserts that the provided compounds are isomers. Isomers share a common molecular formula but exhibit structural or configurational differences. The molecular formulas of the compounds in Statement (I) are examined. If these formulas differ, or if their structural relationship does not conform to the definition of isomerism, the statement is invalid.

Statement (II): Claims the compounds are functional group isomers. Functional group isomers are compounds with identical molecular formulas but distinct functional groups. The provided structures are inspected, focusing on their functional groups and molecular formulas. If the functional groups are different while the molecular formulas remain the same, they are indeed functional group isomers. Otherwise, the statement is invalid.

Analysis:

Evaluation Parameter	Statement I Assessment	Statement II Assessment
Molecular Formula Match	Absent	Present, but functional group differentiation is flawed
Structural/Functional Group Conformity	Non-compliance with isomerism criteria	Incorrect; proposed functional group alteration is not evident

Conclusion: Based on the evaluation of both molecular formulas and structural comparisons, neither statement satisfies the conditions for isomerism. Consequently, Statements I and II are both determined to be false.
