you separate them. The two carbonyls react and form the aldol. Our product was trans-p-anisalacetophenone and it was produced from the ketone reacting with the aldehyde. The ketone does not react with itself because the aldehyde is sterically favored and the carbon on it is more likely to be attacked by the nucleophile than the carbon on the ketone. If the ketone were to attack itself‚ much more

is truly sputum and not saliva. Urine culture: since most urinary tract infections are caused by gram-negative bacilli‚ identification and sensitivity testing are of primary importance. Usually‚ identification of bacteria and determination of their sensitivity to specific antimicrobial drugs are done after the initial gram stain analysis. Most frequently‚ the identification of a specific organism must be accompanied by a sensitivity study. Also due to the changing patterns of resistance in other

Infrared Spectroscopy Organic Chemistry Lab 301A B. The purpose of this lab is to study Infrared Spectroscopy‚ which focuses on the study of the electromagnetic spectrum. The area to be studied is the infrared region‚ which is made up of gamma‚ X‚ and UV rays. We want to be able to identify spectra’s to their complementary structures. The background of this experiment particularly deals with the study of compound structure determination‚ and traits. We must be aware of the functional groups

Endocrine Case Histories - Case 28 A 21-year-old noncompliant male with a history of type I (insulin-dependent) diabetes mellitus was found in a coma. His blood glucose was high‚ as well as his urine glucose‚ urine ketones‚ and serum ketones. His serum bicarbonate was <12 mEq/L. His respiration was exaggerated and his breath had an acetone odor. His blood pressure was 90/60 and his pulse weak and rapid (120). ------------------------------------------------- Top of Form 1. Define noncompliant

Her bowel sounds were extremely active‚ some pain in the upper-central abdomen‚ and a urine analysis which confirmed ketonuria or for the abnormal amount of ketones. As a result‚ she was sent to the intensive care unit for metabolic acidosis or when the body makes too much acid or when the kidneys are not sufficient when removing acid from the body. There are four things that are when ingested‚ are known to cause

New diet programs seem to crop up almost every month‚ so much so that at times I find it difficult to remember all of them. A new kid on the block is the Ketogenic Diet. You may or may not have heard of it because it hasn’t been able to reach the popularity levels of Atkins Diet or South Beach diet. Nonetheless‚ weight loss has little to do with the popularity of a particular diet program. In my experience I have found that people have lost weight with little known diet programs‚ and the opposite

To classify a carbonyl compound by a simple test and to identify it by the precipitation of a derivative. Principle In this experiment‚ the unknown compound is either an aldehyde or a ketone from Table 90. In the first part‚ on undergoing Tollen’s & Fehling’s tests‚ ketone will have no reaction. In the second part‚ by preparing a derivative of the compound with 2‚4-dinitrophenylhydrazine‚ the sharp melting point can be used to identify the unknown carbonyl compound.

observations were used to determine the functional group that was in the unknown‚ the quantitative results were used to determine the molar mass through Duma’s method. The types of compounds that were used in testing were all functional groups‚ Aldehyde‚ Ketone‚ Alcohol and‚ Ester. Functional groups are a portion of a molecule that give the molecules its properties‚ they are the centers of chemical reactivity. The structures of the functional groups used in testing are displayed in Figure 1.0.
