Bottles containing C6H5I and C6H5CH2I lost their
original labels. They were labelled A and B for testing.

with NaOH solution. The end solution in each tube
was made acidic with dilute HNO3 and some AgNO3
solution added. Solution B gave a yellow ppt. which

Replacement of ‘Cl’ of chlorobenzene to give phenol
requires drastic conditions but chlorine of 2,4-
dinitrochloro benzene is readily replaced because
1. NO2 makes the ring electrons rich at ortho and
para position
2. NO2 withdraws electrons from meta position
3. NO2 donates electrons at m-position
4. NO2 withdraws electrons from ortho and para
positions
