Answer:
a. Yes, there was a difference in the number of times your substrate underwent addition in the two Friedel-Crafts reactions.
b. There was a difference- due to the fact that the first added alkyl group increaseD the electron density on benzene ring.
Explanation:
Yes, there was a difference in the number of times the substrate underwent addition in the two Friedel-Crafts reactions .
There was a difference - There was an increase in the rate of second Friedel-Craft reaction due to the fact that the first added alkyl group increaseD the electron density on benzene ring.
Therefore the rate of the addition reaction increases.
