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.

The most important chemical reaction of alkanes is probably combustion, where they react with oxygen to produce carbon dioxide and water, releasing heat energy. This reaction is important because it is used for energy production in engines, heating systems, and other applications.
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.
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.
alkenes are neutral nucleofiles they undergoes electrophilic addition reactions.
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.

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.
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.
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.
No, because alkanes are saturated, meaning they don't have any double bonds. Therefore there are no spare bonds to form polymers, which are plastics. Remember, monomers are single reactive molecules, and because alkanes have only one bond, they aren't very reactive and it takes a lot of energy to break them apart! Hope this helps!! :)
The acidity of an alkane refers to its ability to donate a proton in a chemical reaction. Generally, alkanes are not very acidic and do not readily participate in reactions that involve proton transfer. However, in certain cases where the alkane is functionalized or under specific conditions, it may exhibit some acidity and influence the course of a reaction. Overall, the low acidity of alkanes limits their reactivity in many chemical reactions.

Substances that contain radicals are typically organic compounds, where a radical is an atom or group of atoms with an unpaired electron. Common examples include alkanes, alkenes, and aromatics. Radicals are important intermediates in many chemical reactions.
