Dear arti,

Aromatic compounds burn with sooty flame Due to the more carbon content w.r.t hydrogen of aromatic compounds.

We are all IITians and here to help you in your IIT JEE preparation.

All the best.

Because of the high carbon-hydrogen ratio. A flame is "sootier" when there is less oxygen present in it. In an alkane you have more hydrogen to burn than carbon and 2 hydrogen atoms only require one oxygen to burn. Since CO2 is produced when burning organic compounds one C requires 2 oxygen atoms in order to burn. So when you have more carbons per hydrogens burning, you get a larger consumption of oxygen per area. Less oxygen means sootier flame.
