Question

when ethanol,napthalene and camphor are burnt, which of them produces smoke??

Answer 1

Saturated aliphatic compounds burn with a blue flame whereas aromatic compounds and unsaturated aliphatic compounds burn with a sooty flame or smoke.

Alcohol is a saturated aliphatic compound, so it burns without producing smoke.

Naphthalene and camphor are aromatic, so they burn producing smoke.
