How do you maximize the atom economy?
How do you maximize the atom economy?
Using a lower molecular weight base and/or a higher molecular weight triglyceride would reduce the mass of waste and/or increase the mass of the product, thus increasing the atom economy.

What is the atom economy of a reaction?
The atom economy of a reaction is a measure of the amount of starting materials that end up as useful products. It is important for sustainable development and for economic reasons to use reactions with high atom economy.
What is considered a good atom economy?
Good atom economy means most of the atoms of the reactant are incorporated in the desired products and only small amounts of unwanted by products are formed and hence lesser problems of waste disposal.
How is atom economy used in industry?
Atom economy is a way to measure the amount of useful product made in a reaction. It is a theoretical value that provides another way to evaluate a reaction process, alongside yield and efficiency.
How is atom economy different from yield?
Percentage yield is an experimental value calculated based on obtained results whereas atom economy is a theoretical value measured according to a balanced equation.
What is atom economy Bitesize?
The atom economy of a chemical reaction is a measure of the percentage of reactants that become useful products. Efficient processes have high atom economies, and are important for sustainable development, as they use fewer natural resources and create less waste. …
What is yield and atom economy?
Atom economy and percentage yield. Atom economy is the percentage of the total mass of reactants that successfully converted to the desired product. Percentage yield is calculated from the mass of reactants and the mass of products.
What atom economy is considered green?
In this example all the atoms of the reactants (9 and 11) are shown in green since all of these atoms are utilized in the final desired product (7). The table of atom economy (Table 6) and the calculation of 100% atom economy further emphasize the excellent atom economy of this reaction.
Why is a higher atom economy better?
The atom economy of a chemical reaction is a measure of the percentage of reactants that become useful products. Efficient processes have high atom economies, and are important for sustainable development, as they use fewer natural resources and create less waste.
Do you include solvent in atom economy?
Atom economy also must consider substances such as solvents, separation agents and drying agents that are used in the process but are not directly part of the chemical reaction. In an ideal chemical process, the amount of starting materials or reactants equals the amount of all products generated and no atom is wasted.
Why is percentage yield and atom economy important?
Percentage yield tells us how much of our reactants have been successfully converted into products, while atom economy tells us how many atoms in the reactants have been converted into our desired product. Both are important factors to consider if you are manufacturing a product using a chemical reaction.
Why is the atom economy important in chemistry?
It is important for sustainable development and for economic reasons to use reactions with high atom economy. The percentage atom economy of a reaction is calculated using this equation: The highest possible value of atom economy is 100%, when all the reactant atoms end up in the desired product.
What is the correct electron configuration for copper (Cu)?
Correct Electron Configuration for Copper (Cu) Half-filled and fully filled subshell have got extra stability. Therefore, one of the 4s2 electrons jumps to the 3d9. This give us the (correct) configuration of: 1s2 2s2 2p6 3s2 3p6 3d10 4s1. For the Cu+ ion we remove one electron from 4s1 leaving us with: 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10
What is the relationship between the percentage yield and atom economy?
The percentage yield shows how much product is obtained compared to the maximum possible mass. The atom economy of a reaction gives the percentage of atoms in reactants that form a desired product. No atoms are created or destroyed in a chemical reaction. However, the atoms in the reactants may not become the desired product.
What is the maximum possible value of atom economy?
atom economy = × 100. The highest possible value of atom economy is 100%, when all the reactant atoms end up in the desired product. If the atom economy is 50%, for example, then half the reactant atoms end up in the desired product or products.
