· Take
some carbon compounds (naphthalene, camphor, alcohol) one by one on a spatula
and burn them.
·Observe
the nature of the flame and note whether smoke is produced.

Discussion:
We observe that camphor and alcohol burn with a blue luminous flame and there
is no sooty deposit on the metal plate. So this indicates that camphor and alcohol are saturated
compounds.
On the other hand, naphthalene burns with
a yellow flame with lots of black smoke. Therefore, naphthalene is an
unsaturated compound.
Conclusion:
This activity shows that saturated compounds burn with a luminous blue flame
white unsaturated compounds burn with a yellow sooty flame.
