What type of reaction occurs when two alkenes undergo addition reactions?

• A. Nucleophilic substitution
• B. Electrophilic addition
• C. Radical polymerization
• D. Condensation reaction

Answer: (B)

When two alkenes undergo addition reactions, the process typically involves the breaking of the π bond in the alkene and the formation of new σ bonds with other reactants. This is primarily characterized as an electrophilic addition reaction. In electrophilic addition, an electrophile attacks the electron-rich double bond of the alkene, resulting in the formation of a more stable carbocation intermediate. This is followed by a nucleophile attacking the carbocation formed, which leads to the complete conversion of the alkene into a saturated compound. For alkenes, this process allows for the introduction of various functional groups onto the carbon framework by adding atoms or groups to the respective carbons that were originally part of the double bond. This type of reaction is crucial in organic synthesis as it expands the complexity of organic molecules and is foundational in the creation of diverse chemical compounds. The other options do not fit the context of the reaction occurring with alkenes specifically undergoing addition reactions, emphasizing why electrophilic addition is the correct choice.
