What type of reaction is exhibited by alkenes?
Alkynes undergo many addition reactions such as: catalytic hydrogenation, addition by electrophilic reagents, hydration with tautomerism, hydroboration reactions, and oxidations. They also undergo nucleophilic addition reactions & reduction. Finally alkynes are the strongest bronsted acids made from only hydrocarbons.
Why the remaining mixture of alkanes and alkenes have to discard into water for reaction with sulphuric acid?
The remaining mixture of alkanes and alkenes is discarded into water to separate the alkenes from the alkanes because alkenes are soluble in sulfuric acid and can undergo electrophilic addition reactions, while alkanes do not react with sulfuric acid. Water helps to extract the alkenes, allowing for a clearer separation of the components. Furthermore, this process minimizes the risk of unwanted reactions and ensures that only the reactive alkenes interact with sulfuric acid.
Do aromatic compounds undergo additon reactions?
Aromatic compounds typically do not undergo addition reactions. Their stability is due to the delocalized pi-electrons in the aromatic ring, making them less reactive towards addition reactions. Instead, aromatic compounds often undergo substitution reactions.
When alkenes undergo addition reaction what kind of bond does it produce?
When alkenes undergo addition reactions, they typically form a new single bond, resulting in a saturated compound. This is because the double bond in the alkene is broken, allowing the addition of atoms or groups to each carbon of the original double bond.
Why alkane make good fuels?
Alkanes make good fuels because they have high energy content per unit mass, they undergo combustion reactions that release a large amount of heat energy when burned, and they are relatively abundant and easily obtainable from fossil fuel sources. Additionally, alkanes burn cleanly and produce less pollution compared to other fuel sources.
Does propane undergo addition reaction?
Propane does not typically undergo addition reactions due to its stable structure as a saturated hydrocarbon. It is not reactive under normal conditions and tends to undergo combustion or substitution reactions rather than addition reactions.
What are the key differences between an alkane, alkene, and alkyne in terms of their chemical structures and reactivity?
Alkanes are saturated hydrocarbons with single bonds, alkene have double bonds, and alkynes have triple bonds. Alkanes are the least reactive, while alkenes and alkynes are more reactive due to the presence of double and triple bonds, respectively. Alkenes can undergo addition reactions, while alkynes can undergo both addition and elimination reactions.
How can bromine water test the difference between alkanes and alkenes?
Bromine water can differentiate between alkanes and alkenes because alkenes can decolourize bromine water due to their ability to undergo addition reactions. Alkanes, being saturated hydrocarbons, do not react with bromine water because they lack double bonds to facilitate the addition reaction.

Is halogenation of alkanes a nucleophlic or electrophlic mechanism?
alkenes are neutral nucleofiles they undergoes electrophilic addition reactions.
Why alkanes do not react with bromine water?
Alkanes do not react with bromine water because alkanes are saturated hydrocarbons, meaning they have only single bonds between carbon atoms. This makes them relatively unreactive towards electrophilic addition reactions, such as the reaction with bromine water. bromine water reacts with alkenes, which have carbon-carbon double bonds, through an electrophilic addition reaction.
What is photoactivation of alkanes?
Photoactivation of alkanes is a process where alkanes are activated by irradiation with light, usually UV light, to produce reactive intermediates that can undergo further reactions. This process can lead to functionalization of alkanes, a typically unreactive class of compounds, enabling the introduction of new functional groups. Photoactivation of alkanes is a valuable tool in organic synthesis for generating complex molecules.
Why don't alkanes undergo fluorination?
because halogenation of alkanes with fluorine is very violently exothermic i.e explosive in nature .
Will c6h12 react addition or substitution reactions why?
C6H12 can undergo both addition and substitution reactions, depending on the specific conditions and reagents used. Addition reactions involve the addition of atoms or groups to double or triple bonds, while substitution reactions involve the replacement of one atom or group with another. The type of reaction that occurs will depend on the nature of the reactants and the reaction conditions.
Would C6H12 react by addition or substitution reactions?
C6H12 is a general formula for cycloalkanes, which typically undergo substitution reactions due to the presence of stable sigma bonds within the ring structure. Addition reactions are more characteristic of unsaturated hydrocarbons like alkenes and alkynes.
