Homework Help: chemistry

out of orthonitroaniline and paranitroaniline which one will go at the top of TLC plate and why

It depends upon the stationary phase and the mobile phase, to some extent; however, o-nitroaniline is LESS polar than p-nitroaniline. A polar adsorbent will hold the para isomer more strongly than the orth isomer.
