Green Epoxidation of Chalcones
In this experiment, we will perform a "green" epoxidation of a chalcone using hydrogen peroxide in aqueous sodium hydroxide. We will calculate the percent yield, determine the melting point, and analyze the infrared spectrum of the epoxide product.

Relative Stabilities of Complex Ions
Переглядів 9273 роки тому
In this experiment, we will examine whether the precipitates or complex ions formed by the reaction of hydrated copper(II) ion with a given species can, on addition of a second ligand, be dissolved or transformed to another species. We will then rank the relative stabilities of the precipitates and complex ions made from copper(II) ion with respect to one another, and thus rank the equilibrium ...
Synthesis of Substituted Chalcones
Переглядів 5 тис.3 роки тому
In this experiment, we will prepare a substituted chalcone using the 4-methylacetophenone product from the Friedel-Crafts acylation experiment and 3-nitrobenzaldehyde, a substituted benzaldehyde. You will need to determine the structure of the condensation product that you expect to be formed in the reaction, and the molecular formula of that product.
Friedel-Crafts Acylation

In this experiment, we will perform a Friedel-Crafts acylation of toluene using acetyl chloride. We will calculate the percent yield, determine the boiling point, and analyze the IR spectrum of the product.
Preparation of an Unknown C-4 Acetate Ester
Переглядів 7183 роки тому
In this experiment, we will prepare an ester from acetic acid and an unknown C-4 alcohol. You will need to use the boiling points of the unknown alcohol and its ester, as well as the infrared spectra, to determine the identity of the alcohol and the ester. Once you know the identities of the alcohol and ester, you can calculate the percent yield.

Esters - Identification of Unknowns (Part 8)
Переглядів 1,2 тис.3 роки тому
This is Part 8 of the Identification of Unknowns Organic Qualitative Analysis experiment. In this experiment, we will review the ferric hydroxamate test for esters. Esters are converted to hydroxamic acids upon being heated with hydroxylamine, and the hydroxamic acids form colored complexes with ferric ion.
Alcohols - Identification of Unknowns (Part 7)
Переглядів 6653 роки тому
This is Part 7 of the Identification of Unknowns Organic Qualitative Analysis experiment. In this experiment, we will review the Lucas test for alcohols. This test depends on the appearance of an alkyl chloride as an insoluble second layer when an alcohol is treated with the Lucas reagent. The Lucas test does not work well with solid alcohols or liquid alcohols containing six or more carbons.
Amines - Identification of Unknowns (Part 6)
Переглядів 8883 роки тому
This is Part 6 of the Identification of Unknowns Organic Qualitative Analysis experiment. In this experiment, we will review the nitrous acid test for amines. The nitrous acid test is used to distinguish between primary aromatic and primary aliphatic amines from secondary and tertiary amines.

Переглядів 1,5 тис.3 роки тому
This is Part 3 of the Identification of Unknowns Organic Qualitative Analysis experiment. In this experiment, we will review the Tollens test for aldehydes and the Iodoform test for methyl ketones. These compounds are identified by the distinctive reactions of the carbonyl function. 0:25 = Tollens Test 3:32 = Iodoform Test
Unsaturation Test - Identification of Unknowns (Part 2)
Переглядів 1,4 тис.3 роки тому
This is Part 2 of the Identification of Unknowns Organic Qualitative Analysis experiment. In this experiment, we will review the potassium permanganate test for unsaturation. The potassium permanganate test is positive for double and triple bonds, but not for aromatic rings.
Solubility Tests - Identification of Unknowns (Part 1)
