Bottels containing C6H5I and C6H5CH2I lost their original labels. They were labelled A and B for testing. A and B were separately taken in test tubes and boiled with NaOH solution. The end solution in each tube was made acidic with dilute HNO3 and then some AgNO3 solution was added. Substance B gave a yellow precipitate. Which one of the following statements is true for this experiment?

Question

Bottels containing C6H5I and C6H5CH2I lost their original labels. They were labelled A and B for testing. A and B were separately taken in test tubes and boiled with NaOH solution. The end solution in each tube was made acidic with dilute HNO3 and then some AgNO3 solution was added. Substance B gave a yellow precipitate. Which one of the following statements is true for this experiment? (A) A is C 6H5I (B) A is C6H5CH2I (C) B is C6H5I (D) Addition of HNO3 is unnecessary

In test tube A. <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-qgffe7dj0yx5f6eh.jpg" /> In test tube B . C6H5CH2I arrow - C6 H5 CH2 OHNaOH , boil NaI arrow (. ii .) (AgNO)3(. i .) Dil (HNO)3 AgI (yellow ppt.)

$A$ is $C_6 H_{5} I$

$A$ is $C_{6} H_{5} C H_{2} I$

$B$ is $C_{6} H_{5} I$

Addition of $H N O_{3}$ is unnecessary

In test tube $A .$
In test tube $B$ .
$C_{6} H_{5} C H_{2} I \to_{- C_{6} H_{5} C H_{2} O H}^{N a O H, b o i l}$ $N a I$ $\to_{(ii) (A g NO)_{3}}^{(i) D i l (H NO)_{3}}$ $A g I$ (yellow ppt.)

A is C_6H5​I

A is C6​H5​CH2​I

B is C6​H5​I

Addition of HNO3​ is unnecessary

In test tube A. In test tube B . C6​H5​CH2​I→−C6​H5​CH2​OHNaOH,boil​ NaI →(ii)(AgNO)3​(i)Dil(HNO)3​​ AgI (yellow ppt.)

$A$ is $C_6 H_{5} I$

$A$ is $C_{6} H_{5} C H_{2} I$

$B$ is $C_{6} H_{5} I$

Addition of $H N O_{3}$ is unnecessary

In test tube $A .$
In test tube $B$ .
$C_{6} H_{5} C H_{2} I \to_{- C_{6} H_{5} C H_{2} O H}^{N a O H, b o i l}$ $N a I$ $\to_{(ii) (A g NO)_{3}}^{(i) D i l (H NO)_{3}}$ $A g I$ (yellow ppt.)
