Given below are two statements: Statement (I): [cyclopentane structure] and [an alkene chain structure] are isomeric compounds. Statement (II): [a straight-chain primary amine structure, NH2 at the end] and [a secondary amine structure, NH linked between two alkyl groups] are functional group isomers. In the light of the above statements, choose the correct answer from the options given below : (1) Both Statement I and Statement II are false (2) Both Statement I and Statement II are true (3) Statement I is true but Statement II is false (4) Statement I is false but Statement II is true

1. Both Statement I and Statement II are false
2. Both Statement I and Statement II are true
3. Statement I is true but Statement II is false
4. Statement I is false but Statement II is true

Correct answer: Both Statement I and Statement II are true

Solution

Both statements correctly describe isomerism: cyclopentane and an alkene chain are structural isomers due to different connectivity of atoms, while the straight-chain primary amine and the secondary amine are functional group isomers as they differ in the type of functional group present.
