Question

Give reason for the following. Ethyne burns with a yellow flame and lots of black smoke

Answer 1

Explanation:

Unsaturated hydrocarbons like ethyne, also known as acetylene, burn to produce a yellow, sooty flame due to incomplete combustion in air. The flame is sooty because the percentage of carbon is comparatively higher than that of alkanes and so does not get completely oxidized in air.
