Question

when napthalene, comphor and alcohol are taken separately and burned one after another separately, which will give a yellow sooty flame and which will give a blue flame? give reason for your answer​

Answer 1

Explanation:

Camphor and napthalene will give a yellow sooty flame because they are unsaturated. Unsaturated compounds generally give out yellow sooty flame.

Alcohol will give blue non sooty flame because it is saturated. Saturated compounds give blue clean flame under complete combustion.
