Releted Question 2
Bottles containing $${C_6}{H_5}I$$ and $${C_6}{H_5}C{H_2}I$$ 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 $$HN{O_3}$$ and then some $$AgN{O_3}$$ solution was added. Substance B gave a yellow precipitate. Which one of the following statements is true for this experiment ?
A.
$$A$$ and $${C_6}{H_5}C{H_2}I$$
B.
$$B$$ and $${C_6}{H_5}I$$
C.
Addition of $$HN{O_3}$$ was unnecessary
D.
$$A$$ was $${C_6}{H_5}I$$

C.
by heating phenol with $$HF$$ and $$KF$$
D.
from aniline by diazotisation followed by heating the
diazonium salt with $$HB{F_4}$$
Releted Question 4
