Question: Which reaction mechanism is primarily involved in the addition of HBr to propene?

Options:

Correct Answer: Electrophilic addition

Solution:

The addition of HBr to propene occurs via an electrophilic addition mechanism, where the double bond acts as a nucleophile.

Which reaction mechanism is primarily involved in the addition of HBr to propene?

Step 1: Identify the reactants - In this case, we have propene (a molecule with a double bond) and HBr (hydrobromic acid).
Step 2: Understand the double bond - The double bond in propene is made of two pairs of electrons, making it a nucleophile, which means it can donate electrons.
Step 3: Recognize HBr as an electrophile - HBr can be split into H+ (a proton) and Br- (a bromide ion). The H+ is an electrophile, meaning it can accept electrons.
Step 4: Electrophilic addition begins - The double bond in propene attacks the H+ from HBr, forming a carbocation (a positively charged carbon atom).
Step 5: Bromide ion attacks - The Br- ion then attacks the carbocation, resulting in the addition of Br to the propene molecule.
Step 6: Final product - The final product is an alkyl bromide, where H and Br have added across the double bond.
