Did you notice a difference in the number of times your substrate underwent addition in the two Friedel-Crafts reactions? Why was there a difference or why was there no difference?
Homework Answers
Ans: The rate of second fried craft reaction increases because first added alkyl group increases the electron density on benzene ring. Therefore the rate of the reaction increases.

5. Did you notice that during the action potential the neuron membrane potential reaches -90mV and stops? How/why does it stop at -90mV? Why doesn't it get more negative than -90mV? Hint: When the voltage-gated K+ channels are open on a neuron, there are so many voltage- gated K+ channels open that in reality you can think of the cell as being only permeable to K+. It's the main ion moving. Based on this and what we talked about on...
