Bottles containing C6H5I and C6H5CH2I lost their originallabels. They were labelled A and B for testing. A and B wereseparately 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 followingstatements is true for this experiment ? [2003]
