Chapter 5 Part M_2: Electrophilic Addition Mechanism Example 10 points
The mechanism for the electrophilic addition of HX to an alkene has been established as a two steap reaction sequence. Demonstrate this mechanism by showing both steps in this mechanism using HBr and Ethene at room Temperature. Show curved arrows in the Polar Reaction Mechanism
C2H4 + HBr à CH2BrCH3
a. Step #1:
b. Step #2:
Is there a carbocation reaction intermediate formed in this mechanism? (If so label it in the above mechanism)
In the above label each reactant and product in the two steps as either a nucleophile or and electrophile.
