Question

Saturated hydrocarbons burn with a blue, smokeless flame in the excess of air.

• A. True
• B. False

Answer 1

The correct option is A True

1. Saturated hydrocarbons which are the organic compounds that consist of single bonds will contain low Carbon content.
2. Due to low Carbon content the atmospheric Oxygen is enough to complete the combustion, and so it will burn with a blue flame.
3. The burning will be smokeless if the excess amount of Oxygen is present.
4. While if excess air is not present it gives a smoky flame.
5. Complete combustion of fuel takes place in Saturated hydrocarbon.
6. Hence, the statement is true. Saturated hydrocarbons burn with a blue, smokeless flame in the excess of air.
