Extraction is one of the oldest chemical operations known to humankind. The preparation of a cup of coffee or tea involves the extraction of flavor and odor components from dried vegetable matter with hot water. Aqueous extracts of bay leaves, stick cinnamon, peppercorns, and cloves, along with alcoholic extracts of vanilla and almond, are used as food flavoring…

Extract of sample
Organic Chemistry

The extraction of compounds from these natural products is an example of solid/ liquid extraction-the solid being the natural product and the liquid being the solvent into which the compounds are extracted. In research, a Soxhlet extractor is often used for solid/liquid extraction.
Although solid/liquid extraction is the most common technique for brewing beverages and isolating compounds from natural products, liquid/liquid extraction is a very common method used in the organic laboratory, specifically when isolating reaction products. Reactions are typically homogeneous liquid mixtures and can therefore be extracted with either an organic or aqueous solvent. Organic reactions often yield a number of by products-some inorganic and some organic. Also, because some organic reactions do not go to 100% completion, a small amount of starting material is present at the end of the reaction. When a reaction is complete, it is necessary to do a workup, that is, separate and purify the desired product from the mixture of byproducts and residual starting material. Liquid/liquid extraction is a common separation step in this workup, which is then followed by purification of the product. There are two types of liquid/liquid extractions: neutral and acid/base. ...

Organic Chemistry Essay
The ozonolysis products indicate that C10H14 has two methyl groups and one CH2= group, which form part of the two substituents. With one carbon-carbon double bond outside the six-membered ring, it is safe to assume that the ring is not a phenyl group. With these three possibilities, one would get CH2O as one of the products upon ozonolysis. With options 2 and 3, one would also expect to get a product with a CH3 group as substituent and CH3COCH3, respectively. However, since this is not the case, options 2 and 3 are ruled out.

Chemistry in Daily Life
This world is made up of matter. We human beings are part of matter as we live in this world. Our body is made up of matter of different kinds. Matter is embedded in everything that contributes to protect our life - right from the food we have to the environment we live in. And, from what we eat to where we live, it is all related to chemistry. The human body thrives on organic compounds like proteins, nucleic acids, carbohydrates, vitamins, etc., and defends itself with enzymes such as catalase, reducing agents such as glutathione and cysteine, and we eat antioxidants such as vitamin C, E and…

Cut and paste the diagram here - cite the source and you are done. This reaction will follow the Markonikov rule however since both the carbons around the double bond have equal number of hydrogen's replaced the halide will attach to the carbon with the lowest number in the chain.

A careful look at the peaks results displayed by the NMR of the substance is also required. A singlet peak at a chemical shift value of 11.1ppm confirms the presence of the COOH group. Peak at 2.4ppm is due to the presence of the group R-C=O attached to CH. Applying the n+1 rule we know that the methylene or the CH2 group will be able to interact with the three hydrogen of the methyl or the CH3 group, hence (3+1)=4 peaks or a quadruplet is obtained. Similarly the three hydrogen atoms of methyl are ale to interact with the 2 hydrogen of methylene, hence (2+1) =3 or a triplet peak is displayed.…

Amine/organic Chemistry
Amines are organic compounds with strong basic property. When hydrogen atoms are replaced by alkyl group, they have strongly basic whereas when they react with aryl group or aryl group replaces hydrogen atom, their basicity decreases. When alkyl amines react with nitrous acid they form unstable diazonium salt but aryl amines like aniline form stable salts with nitrous acids that can be crystallized and is thus more useful.…
