Can alkanes form hydrogen bonds?
1 Answer. The simple answer is none, as alkanes do not engage in hydrogen bonding.

What are the first six alkanes?
D. Alkanes are the simplest hydrocarbon chains. These are organic molecules that consist only of hydrogen and carbon atoms in a tree-shaped structure (acyclic or not a ring)….List the Simplest Hydrocarbons.

Are all alkanes flammable?
In general, alkanes show a relatively low reactivity. Lower alkanes in particular are highly flammable and form explosive mixtures (methane, benzene) with air (oxygen). Solubility of alkanes in water is very low. The physical properties of alkanes follow a similar trend as seen in the regularity of alkane structures.
Do alkanes conduct electricity?
Alkanes do not conduct electricity in any way, nor are they substantially polarized by an electric field. For this reason, they do not form hydrogen bonds and are insoluble in polar solvents such as water.
Why ethene is not possible?
A single carbon atom can make up to four bonds, but by looking at its electron configuration this would not be possible because there are only two electrons available to bond with. The other two are in a lone pair state, making them much less reactive to another electron that is by itself.
What are the properties of alkanes?
Alkanes contain strong carbon-carbon single bonds and strong carbon-hydrogen bonds. The carbon-hydrogen bonds are only very slightly polar. Therefore, there is no portion of the molecule that carries any significant amount of positive or negative charge, which is required for other molecules to be attracted to it.
What is the main use of alkanes?
Use of Alkanes Alkanes are important raw materials of the chemical industry and the principal constituent of gasoline and lubricating oils. Natural gas mainly contains methane and ethane and is used for heating and cooking purposes and for power utilities (gas turbines).
What are the properties of alkenes?
Physical Properties of Alkenes Alkenes are non-polar, and they are both immiscible in water and less dense than water. They are generally soluble in organic solvents. In addition, they do not conduct electricity.
How can we make alkanes reactive?
Alkanes can be burned, destroying the entire molecule (Alkane Heats of Combustion), alkanes can react with some of the halogens, breaking carbon-hydrogen bonds, and alkanes can crack by breaking the carbon-carbon bonds.
