Question

Take some carbon compound (naphthalene,camphor,alcohol ) one by one on a spatula and burn them . Whether smoke is produced

Answer 1

Answer:

Explanation:

Aromatic compounds burn with a sooty flame due to a high carbon concentration. Aliphatic compounds however means straigh-chain compounds and therefore burn depending on the functional group attached to it but I wouldnt specifically say they give off a smoky flame. Sooty/smoky is usually reserved for aromatic compounds.

Answer 2

Smoke production during the combustion of the given materials are as follows -

• Napthalene - Napthalene or C10H8 is a carbon rich chemical compound which produces high amount of carbon dioxide gas as smoke when we burn the the napthalene.

Chemical reaction :

C10H8 + 12O2 ---> 10CO2 + 4H2O

• Camphor - Camphor or C10H16O is also a carbon rich chemical compound which produces carbon dioxide when we burn it.

Chemical reaction :

C10H16O + 27/2 O2 ---> 8 H2O + 10 CO2

• Alcohol - Alcohol also produces carbon dioxide because it has significant amount of carbon molecules in it's chemical structure.

Chemical reaction :

C2H5OH + 3O2 ---> 2CO2 + 3H2O
