Bottles containing C ₆ H ₅ l and C ₆ H ₅ CH 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 HNO ₃ and then some AgNO ₃ solution was added. Substance B gave a yellow precipitate. Which one of the following statements is true for this experiment?

Options

  1. AA and C ₆ H ₅ CH ₂ I
  2. BB and C ₆ H ₅ I
  3. CAddition of HNO ₃ was unnecessary
  4. DA was C ₆ H ₅ I

Correct answer

D. A was C ₆ H ₅ I

Step-by-step solution

C ₆ H ₅ I will not respond to silver nitrate test because C -I bond has a partial double bond character.
