What is the effect of increasing the size of the halogen in haloalkanes on the reactivity? (2023)
Step 1: Understand what haloalkanes are. They are organic compounds that contain carbon, hydrogen, and halogen atoms (like fluorine, chlorine, bromine, or iodine).
Step 2: Identify the halogens in haloalkanes. The halogens can be fluorine, chlorine, bromine, or iodine, and they vary in size.
Step 3: Recognize that as you go down the group in the periodic table, the size of the halogen increases. For example, iodine is larger than chlorine.
Step 4: Learn about bond strength. The bond between carbon and the halogen is called a carbon-halogen bond. Larger halogens form weaker bonds with carbon.
Step 5: Understand that weaker bonds are easier to break. If the bond is weaker, it takes less energy to break it, making the haloalkane more reactive.
Step 6: Connect the dots: As the size of the halogen increases, the bond strength decreases, leading to increased reactivity in nucleophilic substitution reactions.
