Question:
An aromatic compound has molecular formula C₇H₇Br. Give the possible isomers and the appropriate method to distinguish them.
An aromatic compound has molecular formula C₇H₇Br. Give the possible isomers and the appropriate method to distinguish them.
Show Hint
AgNO₃ test distinguishes:
benzyl halides ≠ aryl halides
Updated On: Mar 19, 2026
- 3 isomers; by heating with AgNO₃ solution
- 4 isomers; by treating with AgNO₃ solution
- 4 isomers; by oxidation
- 5 isomers; by oxidation
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Possible aromatic isomers of C₇H₇Br: • o-bromotoluene • m-bromotoluene • p-bromotoluene • benzyl bromide (C₆H₅CH₂Br)
Step 2: Total isomers =4.
Step 3: Distinction: • Benzyl bromide gives immediate precipitate with alcoholic AgNO₃ • Aryl bromides (o-, m-, p-) do not react
