    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.

    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.
