Two bottles containing C6 H5 I and C...

Two bottles containing `C_6 H_5 I` and `C_6 H_5 CH_2 I` lost their original labels.They were labelled as A and B for testing A and B were separately taken in test tubes and boiled with Na OH solution. The solution in each tube was made acidic with dilute `HNO_3` and some `AgNO_3` solution was added .Substance B gave a yellow precipitate. Which of the following statements is true for this experiment : Addition of `HNO_3` was unnecessary, A was `C_6 H_5 I`, A was` C_6 H_5 CH_2 I `, B was `C_6 H_5 I`

A

A was `C_(6)H_(5)I`

B

A was `C_(6)H_(5)CH_(2)I`

C

B was `C_(6)H_(5)I`

D

Addition of `HNO_(3)` was unnecessary

Text Solution

Verified by Experts

The correct Answer is:
A
A is iodoberizerie and B is benzyl iodide: Since benzyl iodide is more reactive towards nucleophilic reactions. So, on boiling.with NaOH solutipn it will undergo hydrolysis to give benzyl alcohol and Nal. This reaction mixture on acidification-followed by reaction with `AgNO_3` gives light yellow precipitate due to the formation of Agl.
