Experiment H: Identification of an Unknown Organic Compound The objective of this lab was straightforward. We were given an unknown compound and we were to perform an IR spectroscopy and as well as NMR spectroscopy. With the IR spectroscopy‚ I was able to name the functional groups I have on my compound and further confirmed my assumptions by looking at the NMR spectroscopy after. The unknown number I was given was number 203. The molecular weight of the compound was 121. From the molecular weight

Flavoring Agents made from Aldehydes and Ketones Peter Konn Mountain State University Chemistry 302 7/31/12 Abstract This paper looks to delve into the chemistry behind ketones and aldehydes as well as related compounds. The endeavor involved looking into the way their bonding influences how they react. It also considers the simple physical properties of these compounds including their reaction with other compounds‚ chemical structures and formulas. The paper also looked to

question: they all use ketones to increase power and optimise athletic performance. In fact‚ exogenous ketones‚ sometimes known as ketone supplements‚ were developed especially for Navy SEALs. The SEALs use a device known as a re-breather‚ instead of typical scuba gear‚ to avoid detection while on their missions. Unfortunately‚ re-breathers can result in seizures due to oxygen toxicity. Extensive research was undertaken to combat this‚ which concluded that exogeneous ketones reduce the likelihood

Aldehyde and Ketone 1. ALDEHYDE Definition: An aldehyde is an organic compound containing a formyl group. This functional group‚ with the structure R-CHO‚ consists of a carbonyl center (a carbon double bonded to oxygen) bonded to hydrogen and an R group‚ which is any generic alkyl or side chain. The group without R is called the aldehyde group or formyl group. Aldehydes differ from ketones in that the carbonyl is placed at the end of a carbon skeleton rather than between two carbon atoms

In this laboratory‚ the data collected from the experiment will be used to graph the titration curves which help to identify an unknown amino acid. IntroductionAmino acids are simple monomers which are strung together to form proteins. Amino acids play a key cellular role in structure and function. Proteins themselves participate in nearly every physiological event in the cell. Since

Notes Aldehydes and Ketones The major similarity between an aldehyde and a ketone is the carbonyl group. A carbonyl group is a carbon atom doubly bonded to an oxygen atom. [pic] Both molecules have a carbonyl group‚ the difference the number of carbons bonded to the carbonyl carbon. An aldehyde will have none or one and a ketone will have two carbons. All aldehydes‚ except formaldehyde‚ will have a hydrogen atom on one side of the carbonyl carbon and at least on carbon on the other side

reasons the ketone diet is beneficial for treating inflammatory disease is because it reverses the effects of the SAD diet. August McLaughlin from Livestrong says‚ “High-glycemic carbs can cause blood sugar irregularities and trigger or worsen inflammatory responses.” (Carbohydrates and Inflammation). High carb diets are creating all of this metabolic derangement with inflammatory responses. Switching from the standard american diet to the ketogenic diet drastically improves symptoms of inflammatory

ALDEHYDES AND KETONES Abstract Aldehydes and Ketones have certain characteristics in common. However‚ both couldn’t exist in the same compound. Some test for the presence of aldehyde was made for this experiment. These tests includes Tollen’s test‚ Benedict’s Test‚ 2-4-dinitrophenylhydrazine and Schiff’s test. All the tests conduted yielded same results‚ that is‚ formalin and benzaldehyde are aldehyde-containing compounds while acetone is a ketone. On the other hand‚ effect of acid concentration

A Report of Experiment 1 Purification and Identification of An Unknown Mixture Aim To separate a mixture of a neutral (ester‚ alcohol‚ ketone‚ aldehyde or ether) and an acidic compound (phenol or carboxylic acid) or a neutral and a basic compound (amine)‚ and to identify the unknown mixture by physical (M.P. or B.P.) and spectroscopic methods (NMR‚ IR and MS). Method The mixture (sample number: 27) was dissolved in 200 mL of CH2Cl2 and then extracted with 10% NaOH. The acid was removed
