(a)
Interpretation:
A reasonable mechanism for the given pinacol rearrangement reaction is to be proposed.
Concept introduction:
The unimolecular elimination (
(b)
Interpretation:
The reason for the carbocation rearrangement for the given reaction is to be explained.
Concept introduction:
In the carbocation rearrangement, the carbocation gains significant stability from resonance delocalization of the charge. Resonance can provide substantial charge stability.

- This addition of HBr to (Z)-2-bromobut-2-ene takes place regioselectively, with the Br preferentially adding to the alkene C that does not already possess a Br atom. (a) Provide a detailed mechanism for this reaction, including initiation and propagation steps. (b) Explain why this regiochemistry is observed. Br Br HBr ROOR Brarrow_forwardPlease provide a complete, detailed curved-arrow mechanism for the following reaction. Include ALL lone pairs and formal charges. Using the mechanism and a few words, explain why the NaOH deprotonates at the a-position and not the b-position or the aldehyde hydrogen. Also, explain why the indicated alkene is formed in the 2nd second rather than the other possible alkene product.arrow_forward(a) Determine all possible products from the following reaction. Also, identify the products as kinetic or thermodynamic products. (b) Also draw a detailed mechanism for the formation of these products. H-CIarrow_forward
