Given below are two statements:
Statement (I): Cyclopentane and pent-1-ene are isomeric compounds.
Statement (II): (ethylamine) and (dimethylamine) are functional group isomers.
(a) Both Statement I and Statement II are false (b) Both Statement I and Statement II are true (c) Statement I is true but Statement II is false (d) Statement I is false but Statement II is true
- a
Both Statement I and Statement II are false
- b✓
Both Statement I and Statement II are true
- c
Statement I is true but Statement II is false
- d
Statement I is false but Statement II is true
Both Statement I and Statement II are true
Statement I — Cyclopentane vs Pent-1-ene:
- Cyclopentane: (cycloalkane)
- Pent-1-ene: (alkene)
Same molecular formula, different structural types → ring-chain isomers → ✅ TRUE
Statement II — Ethylamine vs Dimethylamine:
- : primary amine (), formula
- : secondary amine (), formula
Same molecular formula, different functional group type (1° vs 2° amine) → functional group isomers → ✅ TRUE
Answer: (b) Both statements are true
