Chemistry - STRUCTURAL ISOMERISM Question with Solution | TestHub

(A) CH₃CH₂CH(CH₃)CH₂–CH₃

Different carbon skeleton and substituent position possible → Chain & position isomerism → 3,4

(B) CH₃CH₂CH₂Cl
Solution: Cl can occupy different carbon positions → Position isomerism → 4

(C) CH₃CH₂CO₂H
Solution: Same formula can give ester functional group → Functional isomerism → 1

(D) CH₃CH(OH)CH(Cl)CHO
Solution: Chiral carbon present → optical isomerism → 2
