Does branching add to the surface area?
Branching lowers the boiling point. As the carbon chain length increases, so will the compound’s surface area. The Van der Waals dispersion strength is proportional to the compound’s surface area. The attractive force between molecules is decreased by branching, which decreases their surface area.
What hydrocarbon has the highest boiling point?
Do hydrocarbons have high melting points?
As the chain length (number of carbons) increases, the melting and boiling point of these alkanes slowly increase. Longer chain molecules have higher boiling point because they are more tightly bound together, much like spaghetti strands.
Are larger hydrocarbons more useful?
In general, shorter chains are more efficient than longer ones. Crude oil is primarily used for fuel. These are in greater demand because shorter chain molecules are easier to burn and are less flammable. The smaller fractions of the chain molecules are therefore in high demand
Are smaller hydrocarbons more flammable?
The length of the chain that makes up a hydrocarbon determines its properties. A shorter hydrocarbon is less viscous, more flammable, more volatile and has a lower boiling point than a long chain hydrocarbon
How does the size of a hydrocarbon affect the cleanliness of the flame?
However combustion tends to become less complete the more carbon atoms are in the molecules. This means that a larger hydrocarbon will result in a yellowish, smoky flame. Carbon monoxide or incomplete combustion can occur when there isn’t enough oxygen.
What are the applications of fractional distillation?
Applications of Fractional Distillation
- Fractional distillation is used for the purification of water as well as separating acetone and water.
- Fractional distillation is used in several industries like oil refineries and chemical plants mainly for purification and separation of many organic compounds.
