Erythro-2,3-dibromo-3-phenylpropanoic acid, also known as erythorbic acid, is a chemical compound that belongs to the class of organic acids. It is a white, crystalline solid that is insoluble in water but soluble in alcohol and ether.
Erythorbic acid was first synthesized in the early 20th century by the German chemist Ernst Schmidt. It is derived from glucose, a simple sugar found in many plants and animals. Erythorbic acid is closely related to ascorbic acid, or vitamin C, and has a similar chemical structure.
One of the main uses of erythorbic acid is as a food additive. It is used as a preservative in a variety of foods, including meats, fruit juices, and canned vegetables. Erythorbic acid helps to prevent the oxidation of these foods, which can cause them to spoil or lose their flavor.
In addition to its use as a food additive, erythorbic acid has several other industrial applications. It is used as a reducing agent in the production of pharmaceuticals, dyes, and fragrances. It is also used as a catalyst in the manufacture of plastics and rubber.
Erythorbic acid is generally considered to be safe for consumption. However, some studies have suggested that high levels of erythorbic acid intake may be linked to an increased risk of certain types of cancer, such as breast cancer and colon cancer. More research is needed to fully understand the potential health effects of erythorbic acid.
Overall, erythro-2,3-dibromo-3-phenylpropanoic acid is a useful chemical compound that has a variety of applications in the food and industrial sectors. While more research is needed to fully understand its potential health effects, it is generally considered to be safe for consumption in small amounts.
Please complete any questions as much as you can before posting. Second question is how the heck do you draw a mixture of both erythro and dibromo in the same structure? Please do not ask for help acquiring, preparing, or handling illicit substances or for help with any activity that does not fall within the confines of whatever laws apply to your particular location. Here are three possible products for the addition of bromine to trans-cinnamic acid: erythro-dibromide, threo-dibromide or a mixture of both. Anti-addition mechanism yields erythron 2,3-dibromo-3-phenylpropanoic acid, syn addition yields thero-2-3-dibromo-3-phenylpropanoic acid, and non-stereoselective mechanism which yields a mixture of both erythro and theo products. Again using same product, 2,3-dibromo-3-phenylpropanoic acid? Any infractions will be met with a temporary ban at the first instance and a permanent ban if there is another. Each product consists of a different mechanism. If so then the top left and right images is erythro syn only correct?

Any help is appreciated to get me started! Once filtered, the product will be purified using recrystallization and the melting point will be identified. It is also important that you describe the specific part of the problem you are struggling with. Again we are being asked to draw the structure for syn, anti and a mixture of both. Bonus points: If submitting a picture please make sure that it is clear. Although the percent yield of the experiment was 77%, meaning 22% of the product was lost. We will not do your homework for you, so don't ask.
General Description Dehydrobromination of α,β-dibromohydrocinnamic acid has been studied in liquid ammonia. And the bottom left and right pictures is threo anti only correct? And also draw the structure if I have a mixture of both. Conclusion: The results of this experiment concluded that the addition of bromine of trans-cinnamic acid underwent an anti-addition mechanism. The results indicate that the melting point range of the product was between 100 degrees celsius and 120 degrees celsius. In order to determine the mechanism, a solution of bromine in acetic acid will be added to a solution of trans-cinnamic acid to be separated using vacuum filtration. . Sealed in dry,Room Temperature solubility soluble in Methanol form powder to crystal pka 2.
Is syn the same as threo and anti the same as erythro? : chemhelp
This could have been a result of the product being left in the flask or errors during the recrystallization process. As a result of the melting point is erythron-2,3-dibromo-3-phenylpropanoic acid this means that the mechanism that occured was a result of anti-addition of bromine. Also what would a mixture of syn and anti look like? The melting point of the product will be used to determine which of the three possible products is produced. It is OK if you are a little or a lot! Again all those pictures are fisher? Melting point range: 100-120 C Discussion: The main purpose of this experiment was to determine the product produced from the addition of bromine to trans-cinnamic acid and measure the melting points. Now first question is in the title of this post, so do let me know! Please flair yourself and read over the rules below before posting.
A screenshot is preferable to a picture of your laptop screen. Despite the errors, according to the book, erythron-2,3-dibromo-3-phenylpropanoic acid has a melting point within the experimental range. Based upon the melting point, the mechanism produced erythron-2,3-dibromo-3-phenylpropanoic acid. . . .
