    Aliphatic vs Aromatic, smoky vs sooty
    I had a quick look in the other chemistry threads, I couldn't find anything, perhaps I didn't look hard enough, so I apologise if there's a similar thread already. After Easter, I have an assessed practical.
    Does an aliphatic or aromatic compound burn with a smoky flame?
    Does an aliphatic or aromatic compound burn with a sooty flame?
    The internet gives conflicting advice.

    Aromatic compounds burn with a sooty flame due to a high carbon concentration.

    Aliphatic compounds however means straigh-chain compounds and therefore burn depending on the functional group attached to it but I wouldnt specifically say they give off a smoky flame. Sooty/smoky is usually reserved for aromatic compounds.

    THANK YOU THANK YOU SO MUCH. I've been searching for the answer for over an hour.

    The functional group in the context of my question is OH, I've only just realised it was supposed to be for a particular function group.
