2. Provide the complete mechanism (curved arrows) to show how the product is formed. Include all lone pairs, formal charges, curved arrows, intermediates, and products. You do not need to draw the structures of transition states. If there is a carbocation rearrangement and/or a proton transfer, be sure to include it (them) in your mechanism. (Remember to start by drawing all ionic compounds as ions/drawing out the structure of all reagents, and drawing in all lone pairs.) HCI 3. Which...

However, we can treat these compounds as electron-rich carbanions because of the large difference in electronegativity between carbon and magnesium.

Multistep reaction mechanisms Group Activity Treating (S)-2-butanol with HBr results in the following two step reaction: Step 1: CH3CH(OH)CH2CH3 + HBr ⇌ CH3CH(OH2)CH2CH3+ + Br- Step 2: CH3CH(OH2)CH2CH3+ + Br- ⇌ CH3CH(Br)CH2CH3 + H2O Draw a mechanism for e
Multistep reaction mechanisms Group ActivityTreating (S)-2-butanol with HBr results in the following two step reaction: Step 1: CH3CH(OH)CH2CH3 + HBr ⇌ CH3CH(OH2)CH2CH3+ + Br-Step 2: CH3CH(OH2)CH2CH3+ + Br- ⇌ CH3CH(Br)CH2CH3 + H2ODraw a mechanism for each step. Draw structures for all reactants and products, including correct stereochemistry (wedges and dashes). Show all the curved arrows in each step, and label each curved arrow according to whether it represents proton transfer, loss of a leaving group, nucleophilic attack, or carbocation rearrangement.

1. Take a look at this figure and do the followng:
A. Write the appropriate reaction conditions/reagents listed
over each arrow (Circled in red).
B. There are four stereoisomers shown for intermediate "4" but
only one for "5". The word "resolved" is written over the arrow
between them. What does resolved mean? How might we be converting a
mixture of four structures into only one structure?
C. Write step-by-step...
