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.
What has the higher boiling point C2H6 or C3H8?
C3H8 (propane) has a higher boiling point than C2H6 (ethane) because propane has a larger molecular size and stronger van der Waals forces between its molecules, which require more energy to break and transition to the gas phase.
What types of hydrocarbons are more abundant in higher-octane gasoline?
Higher-octane gasoline typically contains hydrocarbons with more carbon-carbon double bonds, such as aromatic hydrocarbons like benzene, toluene, and xylene. These hydrocarbons have higher resistance to pre-ignition and provide better fuel efficiency in high-performance engines.
Why has bitumen got a higher boiling point than petrol?
Bitumen has a higher boiling point than petrol because it is made up of larger, heavier hydrocarbon molecules with more carbon atoms. These larger molecules require more energy to break the intermolecular forces holding them together, resulting in a higher boiling point compared to the smaller hydrocarbons found in petrol.
Hydrocarbon boiling points increase the number of carbon or decrease?
Boiling points of hydrocarbons generally increase with an increase in the number of carbon atoms. This is because larger hydrocarbons have stronger London dispersion forces due to increased surface area, which requires more energy to overcome during boiling.
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.
Is it true that in fractional distillation of petroleum low-boiling hydrocarbons come out first?
Yes Since they have a lower boiling point, they have a higher vapor pressure - or to be more exact, a higher fugacity, than the higher boiling point components at the same temperature.
What effect does increasing the number of carbons have on the boiling point?
Increasing the number of carbons in a molecule increase the boiling point in the wast majority of cases.
What are the different hydrocarbons called with different numbers of carbons?
First of all the basic different hydrocarbons are Alkanes, Alkenes , & Alkynes. Their names end in '-ane', '-ene' and 'yne', respectively. There are more complex hydrocarbons, such as Benzene(Phenyl) & 'Cyclo-', but for the moment I'll omit these. Next the number of carbons in the chain gives the basic name. Meth = 1 carbon Eth = 2 carbons Prop = 3 carbons Buta = 4 carbons Penta = 5 carbons Hexa = 6 carbons Hepta = 7 carbons Octa = 8 carbons Nons = 9 carbons Deca = 10 carbons So a hydrocarbon , with single bonds, and with two carbons is Ethane A hydrocarbons, with one double bond and three carbons is Propene A hydrocarbon, with one triple bond and four carbons is either But-1-yne or But-2-yne , depending on which carbon in the chain the the double/triple bond starts at. Petroleum/Gassoline is Octane. Benzene is a 6 carbon cyclic ring, with ,???three double bonds,. This a unique arrangement. Other cyclic hydrocarbons are ;- Cyclohexane , Cyclohexene. and Cyclohex-1,3-diene. There are many more. Hopefully that gives a little insight in to the nomenclature (naming system) of hydrocarbons; The IUPAC authority have designed the nomenclature so that the name gives all the elements, structure and position of the atoms in organic compounds.
What has the higher boiling point C2H6 or C3H8?
C3H8 (propane) has a higher boiling point than C2H6 (ethane) because propane has a larger molecular size and stronger van der Waals forces between its molecules, which require more energy to break and transition to the gas phase.

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 does the chain length of Hydrocarbons change their properties?
As the chain length of hydrocarbons increases, their boiling point and viscosity also tend to increase. Longer chain hydrocarbons are usually less volatile and have higher boiling points compared to shorter chain hydrocarbons. Additionally, longer chain hydrocarbons are typically more viscous and have higher melting points.
What is the difference between a short-chain and a long-chain hydrocarbon?
short chain hydrocarbons have a low boiling and melting point whereas high chain hydrocarbons have a higher boiling and melting point. Also, short chain hydrocarbons have a low density and higher ones have a higher density. :)
How does the size of and number of atoms contained in a hydrocarbon affect its properties?
As the base number of carbon atoms in a simple hydrocarbon increases, the higher the potential energy contained in the compound. More complex hydrocarbons can also have shifting melting and boiling ranges.
