Bromobenzene is prepared by the action of bromine on benzene in the presence of Lewis acid catalysts such as ferric bromide.. Bromobenzene is used to introduce a phenyl group into other compounds. Also please don't use this sub to cheat on your exams!! Benzyl alcohol can be synthesized from bromobenzene and simple organic/inorganic reagents. This reagent can be used, e.g. in the reaction with carbon dioxide to prepare benzoic acid. I just checked the lab book again and the numbers are correct. One method involves its conversion to the Grignard reagent, phenylmagnesium bromide. One method involves its conversion to the Grignard reagent, phenylmagnesium bromide.This reagent can be used, e.g. For Bromobenzene: 0.70mL bromobenzene * (1.495g/mL) *(1 mol / 157.01g) = 0.00667 mol bromobenzene For Magnesium: 0.15g Mg * (1 mol / 24.3 g) = 0.00617 mol Mg. Bromobenzene is used to introduce a phenyl group into other compounds. Part 1 out of 2 Bromobenzene and magnesium form benzoic acid in a 1:1 mol ratio. New comments cannot be posted and votes cannot be cast. Draw the compounds to show how benzyl alcohol can be synthesized. Where is this 122.12 g/mol coming from? Press J to jump to the feed. Bromobenzene is prepared by the action of bromine on benzene in the presence of Lewis acid catalysts such as ferric bromide.
Press question mark to learn the rest of the keyboard shortcuts. The numbers you've provided would imply that magnesium is the limiting reagent as there are fewers moles magnesium compared to bromobenzene. You should be putting your reagents in terms of mols; you can't compare grams of one substance to grams of another.  Other methods involve palladium-catalyzed coupling reactions such as the Suzuki reaction. It is a reagent in organic synthesis. Bromobenzene is used as a precursor in the manufacture of phencyclidine. Bromobenzene + Magnesium --> Phenylmagnesium Bromide, In the experiment I used 0.70mL bromobenzene and 0.15g Magnesium turnings, 0.70mL bromobenzene * 1.495 g/mL * (1 mol / 157.01g) * 122.12 g/mol = 0.814g benzoic acid, 0.15g magnesium * (1 mol / 24.3g) * 122.12 g/mol = 0.754 g benzoic acid, Does this make magnesium the limiting reagent? I would check to make sure that your starting amounts are correct and after that I would ask to see someone else's calculations so you can see why you are getting a different result compared to them; worry less about what result they got and more about how they got it. Get more help from Chegg.
Make pentane from butane c. Make tert-butyl alcohol from butane d. Make formaldehyde from methane. The numbers you've provided would imply that magnesium is the limiting reagent as there are fewers moles magnesium compared to bromobenzene. Chloroacetate + Cyclohexanone, + Chlorobenzene, + Bromobenzene, or + Benzyl Alcohol at (298.15, 303.15, and 308.15) K". Photochlorination (4,092 words) exact match in snippet view article find links to article mono-substituted benzyl chloride. Make benzyl alcohol from bromobenzene b. If they got their answers erroneously, forget about it. I'm confused because everyone else is saying that the bromobenzene is the limiting reagent. Synthesis and reactions. It is a colourless liquid although older samples can appear yellow. This is apparently a thing now that people are writing exams from home.
Bromobenzene is an aryl halide, C6H5Br. Post your questions about chemistry, whether they're school related or just out of general interest. in the reaction with carbon dioxide to prepare benzoic acid. , For liver toxicity, the 3,4-epoxide are proposed intermediates. Journal of Chemical & Engineering.
Animal tests indicate low toxicity. Please do not post entire problem sets or questions that you haven't attempted to answer yourself.  Little is known about chronic effects.
