ans-\Saturated hydrocarbons burn with a blue flame while unsaturated hydrocarbons burn with a sooty flameUnsaturated hydrocarbons like ethyne, also known as acetylene, burn to produce a yellow, sooty flame due to incomplete combustion in air. The flame is sootybecause the percentage of carbon is comparatively higher than that of alkanes and so does not get completely oxidized in air.
