What is the physical state of the smallest alkanes at room temperature?
Alkanes with a carbon chain of 5 up to 17 are liquids. So the set of liquid alkanes begins with pentane, C5H12.
What are 3 uses of alkanes?
Three uses of alkanes are:used as organic solvents in labs when in liquid formused as a general anaestheticused as fuels because a large amount of energy is released when alkanes undergo combustion.
Are organic liquid vapors flammable?
Methane and octane, both alkanes, are examples of gases that are used as fuel and are highly flammable.
Why are alkanes liquefied?
Alkanes are liquefied by cooling them below their boiling points, causing their intermolecular forces to weaken, allowing the molecules to move more freely and transition from a solid to a liquid state.
What come from crude oil alkanes or alkenes?
alkanes
Do alkanes contain phosphorus?
No. alkanes contain only hydrogen and carbon.
Are longer chain alkanes more flammable than shorter chain alkanes?
Shorter chain alkanes are generally more flammable than longer chain alkanes. This is because shorter chain alkanes are more volatile and readily vaporize, making them easier to ignite. Longer chain alkanes are less volatile and require higher temperatures to vaporize and ignite.
What is petroleum gel?
It is a mixture of high molecular weight liquid alkanes. It could be used, biologically, to soften and moisten skin. It is also called "Vaseline".
Hydrocarbons which have only single bonds between carbon atoms?
Alkanes are hydrocarbons that have only single bonds between carbon atoms. They are saturated hydrocarbons with the general formula CnH2n+2, where n represents the number of carbon atoms in the molecule. Alkanes are relatively inert and have straight or branched chain structures.
What the advantages of using alkanes?
Alkanes are, 1- good fuel, 2-higer alkanes are good lubricants, 3- they are antiseptic for external use.
What are 3 kinds of carbon chains found in hydrocarbons?
Alkanes alkanes and alkynes
Why alkanes called parafins?
because of their unreactive nature alkanes are called parrafins
