Options:

Correct Answer: Substitution

Solution:

The reaction of a haloalkane with a nucleophile typically results in a substitution reaction, where the nucleophile replaces the halogen.

What type of reaction occurs when a haloalkane reacts with a nucleophile?

What type of reaction occurs when a haloalkane reacts with a nucleophile?

Step 1: Identify the haloalkane, which is a compound that contains a carbon atom bonded to a halogen (like chlorine, bromine, or iodine).
Step 2: Identify the nucleophile, which is a species that has a lone pair of electrons and can donate them to form a bond.
Step 3: Understand that in the reaction, the nucleophile approaches the haloalkane.
Step 4: The nucleophile attacks the carbon atom that is bonded to the halogen.
Step 5: As the nucleophile forms a bond with the carbon, the bond between the carbon and the halogen breaks.
Step 6: The halogen leaves as a halide ion (like Cl-, Br-, or I-).
Step 7: The result is a new compound where the nucleophile has replaced the halogen, which is called a substitution reaction.
