Step-by-step explanation:
1. Non-4-ene and fluorine gas:
Electrophilic addition reactions involve the addition of an electrophile (fluorine, in this case) to a double bond. In this reaction, the double bond in non-4-ene reacts with fluorine to form 4-fluorocyclohexene. This reaction is typical for alkenes.
2. Hexane and oxygen gas:
Combustion reactions occur when a substance reacts with oxygen to produce carbon dioxide and water. In the case of hexane, the combustion reaction results in the formation of carbon dioxide and water, releasing energy in the form of heat and light.
3. Pentan-1-ol and butanoic acid:
Esterification reactions involve the combination of an alcohol and an acid to produce an ester and water. In this case, pentan-1-ol reacts with butanoic acid in the presence of an acid catalyst to form pentyl butanoate and water.
4. Propene and hydrogen gas:
Hydrogenation reactions involve the addition of hydrogen to a double bond, typically with the aid of a catalyst. In this reaction, propene undergoes hydrogenation in the presence of a platinum (Pt) catalyst to produce propane.
These reactions demonstrate different types of organic reactions, showcasing the versatility of hydrocarbons and their derivatives in-forming various products under specific conditions.
