Alkenes have pi bonds that are readily available to react because the strength of a pi bond isn't as strong as a sigma bond. Pi electrons will attack the nucleophile to form the respective carbocation. Alkanes only contain sigma bonds and have no pi electrons to attack a nucleophile. In order for an alkane to become a strong enough nucleophile it must not be sterically hindered (primary carbons prefered to tertiary) and most likely deprotenated by a very strong base ( likely stronger than sodium amide ).
What else can I help you with?
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.
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.
Which compound may be formed when alkanes are cracked?
When an alkane is cracked, alkenes and shorter alkanes are produced.
What is the difference between the carbon groups called alkanes and alkenes?
Alkenes have at least one double bond between two carbon atoms; alkanes don't.
Does addition reaction take place in alkenes?
Yes, addition reactions can take place in alkenes. Alkenes are typically reactive towards addition reactions because they contain π bonds, which can break to allow new atoms or groups to be added to the carbon atoms of the double bond. Examples of addition reactions in alkenes include hydrogenation, halogenation, and hydration.
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.
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.

Why alkenes undergo nucleophilic addition reaction while simple alkenes do not?
Alkenes have pi bonds that are readily available to react because the strength of a pi bond isn't as strong as a sigma bond. Pi electrons will attack the nucleophile to form the respective carbocation. Alkanes only contain sigma bonds and have no pi electrons to attack a nucleophile.

What is the difference in acidity between alkynes, alkenes, and alkanes?
Alkynes are more acidic than alkenes and alkanes. Alkenes are more acidic than alkanes.
What come from crude oil alkanes or alkenes?
alkanes

Is halogenation of alkanes a nucleophlic or electrophlic mechanism?
alkenes are neutral nucleofiles they undergoes electrophilic addition reactions.
Is Hydrogenation is used to convert alkenes and alkynes to alkanes?
Yes, hydrogenation is a chemical reaction process in which hydrogen is added across a double or triple bond in alkenes and alkynes to produce alkanes. This reaction is commonly used in the food industry to convert unsaturated fats into saturated fats.
Which compound may be formed when alkanes are cracked?
When an alkane is cracked, alkenes and shorter alkanes are produced.
What are some examples of alkanes and alkenes?
Saturated oils and waxes are all types of alkanes and alkenes The Ice man ;) Call me ladies... ;')
What differentiates alkenes from alkanes?
alkanes have single covalent bons, alkenes have double :) lol did this while doing chem homework myself
