Answer: Electrophilic addition reaction
Explanation:
Alkenes are compounds which have at least one double bond between the carbon atoms in the molecule. This is an indication of a shortage of hydrogen atoms. The compound is said to be unsaturated. As an unsaturated compound alkene undergoes the following reaction:
-- Combustion reaction
-- Hydrogenation reaction
-- Addition reaction.
The addition reaction of alkenes occur due to the presence of pi electrons in which an electrophile attacks the carbon-carbon double bond to form the addition products. An electrophile is a molecule that has the affinity to react with other molecules containing a donatable pair of electrons.
A typical example of reaction between alkene and acid is in the decolourisation of acidified potassium tetraoxomanganate(VII) with ethene. The oxygen supplied to the reaction breaks the double bond to yield ethane 1,2 diol ( an alcohol).
The reaction of an alkene with the acid has been performed with the carbocation intermediate formation, followed by the nucleophilic substitution reaction.
The alkenes have been the hydrocarbons with the presence of one double bond in the structure. The double bond has been consisted of the pi electrons.
The alkene has been bonded with the pi-electron, thus in the chemical reaction the pi bond-breaking results in the partial negative and positive charge to the carbon atoms. The negative OH group has been the nucleophile that is attracted by the negatively charged carbon atom, and the bond formation results in the alcohol.
The reaction for an alkene with acid has been given in the image attached.
Thus, the reaction of an alkene with the acid has been performed with the carbocation intermediate formation, followed by the nucleophilic substitution reaction.
