Question

Would the calculated percentage yield of the precipitate (dibenzatacetone) be too high, too low, or unaffected by the Inlowing?

You got to add the NCH cm slowing the mature for 4 minute as trected in #10 of the procedure.
O Too high
O Too low
O Unaffected

Answer 1

The calculated percentage yield of dibenzalacetone could be too high if impurities are present in the final product, as impurities would lead to an increased mass and an inflated yield. So the correct answer is too high.

Step-by-step explanation:

The calculated percentage yield of the precipitate (dibenzalacetone) could potentially be too high if proper care is not taken during the experimental procedure.

In the context of organic synthesis such as the 1,3-dipolar cycloaddition reactions or the synthesis of procaine from p-aminobenzoic acid, all reactants and products must be pure.

Any impurities present in the final product can lead to an increased mass and thereby an inflated percentage yield. The concept of theoretical yield vs. actual yield is very important in chemistry, and analytical techniques like ¹H-NMR can confirm the purity of products.
