What kind of intermolecular forces are present in alkenes?
Alkenes display a weak dipole-dipole interactions due to the electron-attracting sp2carbon. Alkenes are a family of hydrocarbons (compounds containing carbon and hydrogen only) containing a carbon-carbon double bond.
What are the strongest intermolecular forces for alkanes?
Stronger inter-molecular van der Waals forces give rise to greater boiling points of alkanes. There are two determinants for the strength of the van der Waals forces: the number of electrons surrounding the molecule, which increases with the alkane’s molecular weight.
What type of bonds are in alkanes?
Alkanes have only single bonds, alkenes contain a carbon-carbon double bond, and alkynes contain a carbon-carbon triple bond.
Do alkanes have London forces?
Alkanes contain only carbon-carbon and carbon-hydrogen bonds. Thus, alkanes are nonpolar, and they interact only by weak London forces. These forces govern the physical properties of alkanes such as solubility and boiling point. Alkanes are not soluble in water, a polar substance.
What are the first 10 alkanes?
These are organic molecules that consist only of hydrogen and carbon atoms in a tree-shaped structure (acyclic or not a ring). These are commonly known as paraffins and waxes. Here is a list of the first 10 alkanes….List the Simplest Hydrocarbons.
| methane | CH 4 |
|---|---|
| propane | C 3H 8 |
| butane | C 4H 10 |
| pentane | C 5H 12 |
| hexane | C 6H 14 |
Do alkanes burn in oxygen?
The combination of alkanes with oxygen generating heat is known as combustion. More precisely, combustion is defined as “a chemical reaction with oxygen in which alkane is converted into carbon dioxide and water with the release of heat energy”.
Do alkanes contain oxygen?
Because alkanes contain only carbon and hydrogen, combustion produces compounds that contain only carbon, hydrogen, and/or oxygen. Like other hydrocarbons, combustion under most circumstances produces mainly carbon dioxide and water.
Why do alkanes burn?
Alkanes generally burn with blue flame or clean flame because the combustion is complete and no unburnt carbon particles are released.
Why do alkanes burn with a blue flame?
What burns with a clean flame?
Alkanes generally burns with a clear flame. They burn in air with a blue and non-sooty flame as the carbon percentage in the alkane is low and it gets oxidized completely in air and that’s why it burns with a clear flame.
What is alkanes general formula?
The general formula for the alkanes is C nH 2n +2, where n is the number of carbon atoms in the molecule.
Which hydrocarbon has the highest viscosity?
Hydrocarbons
| Substance | Molecular formula | Viscosity (μPa·s) |
|---|---|---|
| Methane | CH4 | 11.13 |
| Acetylene | C2H2 | 10.2 |
| Ethylene | C2H4 | 10.28 |
| Ethane | C2H6 | 9.27 |
Does lava have high viscosity?
Even though lava is 100,000 times more viscous than water, it can still flow great distances. When lava has low viscosity, it can flow very easily over long distances. But most importantly, highly viscous lava is associated with explosive eruptions and dangerous pyroclastic flows.
Which has the highest viscosity?
One of the most commonly studied high-viscosity fluids is Pitch (resin) – Wikipedia, which at 25 °C has a viscosity of [1], about 20 billion times the viscosity of water.
What is the SI unit of viscosity?
Pascal-second
Is viscosity a vector?
Viscosity is a scalar quantity. Displacement, force, velocity, and acceleration all have associated directions and are classified as vector quantities.
What is the SI unit of input?
In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second.
What is SI unit of initial velocity?
The SI unit of velocity is meter per second (m/s).
