Incomplete combustion due to high carbon percentage

Vedclass · Answer

(B) Unsaturated hydrocarbons (like alkenes and alkynes) have a higher percentage of carbon compared to saturated hydrocarbons.When they burn in air,the oxygen available is often insufficient for complete combustion.Due to the high carbon content,the carbon atoms do not get fully oxidized to $CO_2$,leading to the formation of unburnt carbon particles (soot).These incandescent carbon particles glow with a yellow flame and are released as black smoke.

Unsaturated hydrocarbons produce a yellow flame with a large amount of black smoke when burnt in oxygen. Give the reason.
