Question

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

Canvas Classes · Accepted Answer

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
