east stable most stable The following are three examples of the relative stability of carbocations in your answer to question 2. Each of these reactions should show a relatively stable carbocation intermediate. (a) The two-step reaction of 1-methylcyclohexene with HBr follows the Markovnikov 3. rule. (b) Choose 1-butanol or tert-butyl alcohol to undergo a 3-step reaction with HBr to form the alkyl bromide. The second step is the S1 formation of a carbocation. (c) Show the one most stable resonance...

If so, show the mechanism (curved arrows) for the rearrangement (including the rearranged cation that is the product of your curved arrows) and explain why it happens. If not, explain why it would not rearrange.

S. Rank the following cations in order of stability (most stable first): 9. Carbocations from alkyl halides are 10. Why SN1 reactions on alkyl halides having the halogen bound to a chiral carbon are normally accompanied by racemisation, while SN2 reactions on such alkyl halides result in inversion of configuration?

In Lab 5 (the transistor/motor lab), you used a “sufficiently high value” resistor (most teams used a 470 ohm resistor) between a digital pin on the Arduino and the base pin of the transistor. One team had a discussion about why that resistor was needed. Student 1: You need that high of a resistor because the drift speed of the electrons is too high coming out of the Arduino, and the resistor slows that down enough to be usable at...
