Question

with what type of flame do unsaturated compounds burn in air?? ​

Answer 1

Answer:

when saturated compounds are burnt in air,they give a clear(blue) flame but the burning of unsaturated compounds(alkenes and alkynes) gives a sooty (yellowish) flame.

Answer 2

there are two kinds of compounds I, e saturated and unsaturated. when a saturated compound is burned then a Blue flame is produced because less carbon content is present and complete combustion accures.

while whenever a unsaturated compound is burned then a yellow flame is produced due to incomplete combustion and high carbon content.
