Question

How to detect aliphatic and aromatic compound in laboratory?

Answer 1

Heya!!

Take the substance in spatula, ignite it. If it burns with sooty flame, it may be aromatic. On the other hand if it burns with non-sooty flame, it may be aliphatic.

Or heat the substance with con. HHO3 and H2SO4. Cool it. Pour the mixture into beaker containing little amount of water. If it is yellow in color it may be aromatic due to nitration of the ring. Mostly aromatic nitrated compounds are pale yellow.

Thanks!
