Hello, why does this reaction occur? Should not the carbonyl simply be converted to an alcohol and leave the double bond untouched. According to my lab TA the double bond should be left untouched.

Why doesn't the Br attack the
double bond? How does this reaction occur?
NBS Br. Me Me heat and peroxide Me Me 阝粼. draw both possible products
Please explain why an alcohol does not appear in the product
of this reaction. I am confused as to where it went according to
this answer.

Explain why dimethyl maleate is converted in high yield to
dimethyl fumarate under the conditions you used. Use thermodynamic
and kinetic arguments to justify your answer.
How does the reaction preformed relate to the isomerization of
retinal in the human eye (which enables vision).
Primer: A major topic covered in the second half of Organic I is the properties and reactivity of alkenes. This lab experiment will provide you with an opportunity to examine alkene reactivity by conducting an isomerization...
Organic chemistry post-lab question: "Why is important
to add the alkyl halide dropwise in your reaction? (Hint: your
reaction is not heated, but you still need a water-cooled
condenser!)" Please answer in detail!
Here is a copy of the experiment, thank you!
The Grignard reaction is an important synthetic process by which a carbon-carbon bond is formed. Magnesium metal is first reacted with an organic halide. The resultant organo-magnesium halide (Grignard reagent) is then combined with a carbonyl compound, ultimately...
why do I use dried hexane? what does it do?

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....

could you also explain why you chose that substance for the empty
spaces and question marks
EXPERIMENT 4 Pre-Lab Assignment Separating a Mixture, Recrystalliration Name Date 1. Complete the following flowchart which shows how to separate a mixture of sand, sodium chloride and acetanilide. Notice that after a separation process (a down arrow) the filtered solids are shown on the left and the filtrate (the liquid) is shown on the right. The terminal step...
just one example/demonstration!
Data needed to be calculated is in highlighted in green boxes.
And I highlighted in red an equation (not sure if thats what you
use to calculate it) And ignore the lab instructions on completeing
a graph!! I already know how to do that in excel, just curious how
Ln (relative rate) and 1/T in K^-1 is calculated by hand*
here is the rest of that lab leading up to the question as I
know its typically...
