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

- Statement (I) is incorrect as the compounds presented are not isomeric. Isomerism is defined by different compounds sharing the same molecular formula but exhibiting distinct structures or functional groups.
- Statement (II) is also incorrect because \( {NH}_2 \) and \( {NH} \) do not represent functional group isomers. 
Functional group isomers are compounds with identical molecular formulas that vary in their functional groups. 
\( {NH}_2 \) constitutes an amine group, whereas \( {NH} \) represents an imine group; however, these are not functional group isomers. 
Consequently, both statements are false.
