Why don't alkanes undergo fluorination?
because halogenation of alkanes with fluorine is very violently exothermic i.e explosive in nature .
What are substitution reactions of Alkane?
Substitution reactions of alkanes involve the replacement of one or more hydrogen atoms with different atoms or groups. This can include halogenation, where hydrogen is replaced by a halogen, or radical substitution, where a radical group replaces a hydrogen atom. The most common substitution reaction of alkanes is halogenation, such as chlorination or bromination.
Why iodination of alkane is very slow?
Iodination of alkanes is slow because it involves breaking strong carbon-hydrogen bonds to form carbon-iodine bonds. This process requires significant activation energy and involves a radical mechanism that is less favorable compared to other halogenation reactions, such as bromination or chlorination on alkanes.
Under what conditions do alkanes and benzene react with halogens?
Alkanes react with halogens (e.g. chlorine or bromine) only in the presence of UV light or heat to form halogenated products. Benzene does not readily react with halogens like alkanes do due to its aromatic stability, but it can undergo halogenation in the presence of a Lewis acid catalyst.
In halogenation of alkanes the reactions at room temperature is slow in dark while it is rapid in sunlight Why?
In the dark, the halogenation of alkanes is slow because it requires the presence of light to initiate the reaction. The reaction becomes rapid in sunlight because the light provides the energy needed to break the C-H bonds and initiate the radical chain reaction. This leads to the formation of reactive halogen radicals that can then further react with alkanes to produce halogenated products.
Which alkanes are liquid?
pentane and other alkanes above it
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.
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
