1. For the following substrates, predict whether a carbocation rearrangement will take place in an SN1/E1 mechanism by first drawing the carbocation intermediate, then deciding if the carbocation will rearrange (can it form a more stable carbocation by hydride or methyl shift?): Carbocation: Sturcture Rearrange? If yes, draw the rearranged product. If no, write No н.с Br Н,с, Cн, 2. For each pair of nucle ophiles, circle which will react faster with CHsl in an Sx2 reaction....

1. Rank the following carbocations in order from most stable (1) to least stable (4). o ó no 8 2. Consider the following carbocation. Would this carbocation undergo a rearrangement? 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.

Each of the following carbocations can undergo a rearrangement to give a more stable carbocation. In each case, draw the structure of the rearranged carbocation, and show the mechanism of the 1,2 hydride shift or 1,2-alkyl shift...
Draw curved arrows to show the movement of electrons in this step of the mechanism.
Acid-catalyzed addition of water to an alkene yields an alcohol with Markovnikov regiochemistry. The electrophilic H+ adds to the sp2 carbon with the most hydrogens to yield the most stable carbocation intermediate, which then adds water to give the product alcohol. Because a carbocation intermediate is formed, rearrangements can occur prior to the addition of water. To avoid the possibility of rearrangement and still give a Markovnikov alcohol, alkenes can instead be treated with mercury(II) acetate in aqueous THF and then subsequently...

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.
