What happens to the boiling points of hydrocarbons as they get bigger?

"volatile" means it turns into gas more easily. liquids turn into gasses when the temperature increases and all the bonds break apart. the smaller the hydrocarbon chains,the fewer bonds that need to break so the faster it will turn to gas.

What compounds would have the highest boiling points?
ionic
What do the term boiling point snd freezing point mean?
It means boiling points are hot and freezing points are cold.
What has a low boiling point?
Simple hydrocarbons, like methane and ethane. As the carbon chain gets longer, the boiling point goes up. -------------- Some elements, such as helium, hydrogen, nitrogen and neon have extremely low boiling points. Please see the link.
Which type of compound would have the lowest melting point?
Compounds bonded by covalent bonds do not necessarily have low melting points. Some have whereas some don't have.Some polymers and hydrocarbons have very high melting points. But it can be said that they don't have melting points as high as ionic compounds. It is so because ionic bonds are stronger than the covalent bonds.
What are the boiling and melting points of bromine?
Boiling point 58.78°C Melting point 7.2°C
Fractional distillation is used to separate hydrocarbons The process is based on?
boiling points
What is a mixture of hydrocarbons with different boiling points called?
Also a mixture, not a special name.
What physical property of hydrocarbons is used for fractional distillation?
If the hydrocarbons are in the liquid state then their differential boiling points are used in separation - fractional distillation. Some hydrocarbons are also separated by their differential solubility in some organic solvents. =)
Hydrocarbon boiling points increase the number of carbon or decrease?
the boiling points decrease on hydrocarbons as the length of the chain and the weight increases. the melting points increase with length and weight increase. Hope this helps.
How are different hydrocarbons separated by fractional distillation at an oil refinery?
Separation is based on the differences between boiling points.
What property of hydrocarbons lets fractional distillation of crude oil work?
The boiling points of chemical compounds are different.
Do long hydrocarbons have a higher boiling point then short hydrocarbons?
This is true as far as we are talking about alkanes. As the size of an alkane chain increases the boiling point increases because the relatively low van der Waals forces increase with mass. The higher the vdw forces the more energy required to break apart two molecules and thus higher boiling points.
Why are different hydrocarbons have different melting points?
hydrocarbons have different boiling point, the greater the size, the higher the boiling point. This is easily explained by if you imagine a bowl of spaghetti- it is easier to pull out a small strang (it takes less energy). It is the same with hydrocarbons hope that helps
How is crude made into products?
Crude oil contains mixture of various types of hydrocarbons. The hydrocarbons are separated by fractional distillation. Different hydrocarbons have different boiling points and therefore after crude oil is heated, shorter chains of hydrocarbons which have lower boiling point will become gas and can be easily separated one by one from hydrocarbons with shorter chains to longer chains. The brief products are Petroleum Gas, Gasoline, Kerosone, Heating Oil, Lubricating Oil and Bitumen in order of increasing molecular size.
Do small hydrocarbons have with only a few carbon atoms have low or high boiling points?
The lower the carbon chain, the lower the melting point. As the carbon chain gets longer (ie: larger hydrocarbons), the melting point gets higher.
Explain why the boiling points of hydrocarbons that have the generic formula CnH2n plus 2 increase with molecular weight?
because the induced dipole-induced dipole forces are increased.
What mixture separated by fractional distillation?
fractional distillation is used in oil refineries to separate crude oil into useful substances (or fractions) having different hydrocarbons of different boiling points.
