|
List-I Structure of ether |
List-II Common name |
|

(I) Methyl n-propyl ether |
|
(B) \( C_6H_5O(CH_2)_6CH_3 \) |
(II) Methyl phenyl ether |
|
(C) \( C_6H_5OCH_3 \) |
(III) n-Heptyl phenyl ether |
|
(D) \( CH_3OCH_2CH_2CH_3 \) |
(IV) Ethyl phenyl ether |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A)-(IV), (B)-(III), (C)-(II), (D)-(I)
The common name of an ether is formed by naming the two alkyl or aryl groups on the oxygen as separate words, in alphabetical order, followed by the word “ether”.
(A) \(C_6H_5OCH_2CH_3\) — This matches (IV) Ethyl phenyl ether. The groups are ethyl and phenyl.
(B) \(C_6H_5O(CH_2)_6CH_3\) — This matches (III) n-Heptyl phenyl ether. The chain \( \ce{(CH2)6CH3} \) has seven carbons in a straight chain, the n-heptyl group.
(C) \(C_6H_5OCH_3\) — This matches (II) Methyl phenyl ether. The groups are methyl and phenyl.
(D) \(CH_3OCH_2CH_2CH_3\) — This matches (I) Methyl n-propyl ether. The groups are methyl and a straight-chain propyl.
Shortcut: (A)-(IV) appears only in Option (1).
