List - I List - II (A) CH 3 ​ − CH 2 ​ − O − C H 2 ​ − C H 3 ​ and CH 3 ​ − O − C H 2 ​ − C H 2 ​ − C H 3 ​ (P) Chain isomer (B) CH 3 ​ − CH 2 ​ − OH and CH 3 ​ − O − CH 3 ​ (Q) Position isomer (C) CH 3 ​ − CH 2 ​ − C H 2 ​ − C H 3 ​ and (R) Functional group isomer (D) and (S) Metamer (T) Geometrical isomer

TestHub · Accepted Answer

(A) CH₃CH₂–O–CH₂CH₃ and CH₃–O–CH₂CH₂CH₃ are Metamers (S) because both are ethers but alkyl groups on either side of O are different.

(B) CH₃CH₂OH and CH₃–O–CH₃ are Functional Group Isomers (R) (alcohol and ether).

(C) n-Butane and isobutane are Chain Isomers (P) because carbon skeletons are different.

(D) The two alkenes differ in the arrangement of groups around the C=C bond, so they are Geometrical Isomers (T).
