Bottles containing `C_(6)H_(5)I` and `C_(6)H_(5)-CH_(2)I` lost their original lables. They were labelled A and B for festing. A and B were separately taken in a test tube 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.A. Addition of `HNO_(3)` was unnecessaryB. `(A)` was `PhI`C. `(A)` was `PhCH_(2)I`D. `(B)` was `Phl` |
Answer» Correct Answer - `b` Aryl halide, due to resonance does not give test for halide ion, whereas benzyl halides give due to the formation of benzyl `C^(o+)` which gives benzyl alcohol and `I^(theta)`. `Ph I + Aq. NOH rarr "No reaction"` `PhCH_(2)I + Aq. NaOH rarr PhCH_(2) OH + underset(("yellow ppt."))underset(AgI)underset(darr AgNO_(3))underset(l)(I^(theta)` |
