Download file to see previous pages 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.
Amines have strong odour. When they alkyl group replaces hydrogen, the resulting compounds are often extremely foul smelling like decaying flesh and fish and have names like cadaverine and putresine. But, the aryl amines are aromatic.
Amines are extremely important compounds that are extensively used in biological applications and industries. In the body metabolism, amino acids are broken down to form amines that form part of neuro-transmitters like histamine, dopamine, serotonine etc. The amino acids are used to make protein which is essential to the development processes of human body. Many amine drugs are also used for decongestion, anti-histamine to provide relief from allergy like cold, hey fever, anti-depressant etc.
Primary aromatic amines are used as a starting material for the manufacture of azo dyes. It reacts with nitric(III) acid to form diazonium salt, which can undergo coupling reaction to form azo compound. As azo-compounds are highly colored, they are widely used in dyeing industries (wikipedia). Amines are also used in refinery units to purify gas streams and remove carbon-dioxide and hydrogen sulphide. Amines are also used to remove carbon-dioxide from the combustion ...Download file to see next pagesRead More

Organic Chemistry

...Chapter 7: Extraction is one of the oldest chemical operations known to humankind. The preparation of a cup of coffee or tea involves the extractionof 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. For the past 150 years or so, organic chemists have extracted, isolated, purified, and characterized the myriad compounds produced by plants that for centuries have been used as drugs and perfumes-substances such as quinine from cinchona bark, morphine from the opium poppy, cocaine from coca leaves, and menthol from peppermint oil. The extraction of compounds... from these...

Asymmetric Synthesis

...THE SIGNIFICANT RELATIONSHIP OF THE CATALYTIC ASYMMETRIC SYNTHESIS OF CINCHONA ALKALOIDS TO ITS INDUSTRIAL USES With man's present need to acquire significant instruments for the effective asymmetric synthesis of compound organic molecules, the study of catalytic asymmetric synthesis has become an important aspect of organic chemistry. Generally, popular catalysts which are usually used by organic chemists utilize transition metals in order to trigger a chemical reaction in the presence of a chiral ligand (Noyori, 1994.) However, as modern chemistry continues to discover catalytic systems which are organic, the popularity of cinchona...

...Hardy Weinberg and Chi Square Model The Hardy Weinberg Law provides us with the tools to establish allele frequencies in a specific population. There are a some criteria that the population in question must meet. The population cannot be subjected to migration, mutation, genetic drift or selection. Also, the population will need to mate at random. If a population meets these standards, we can use the formula p^2 + 2pq +q^2 to quantify genotype frequencies. We will then say that p^2 = homozygous dominant individuals, allow p to represent the square root of the number used for p^2. Also, allow q^2 to equal homozygous recessive individuals, which means that q = the square root of the number that equals q^2. Finally, we can... Weinberg and ...

Modern Methods of Organic Synthesis

...Synthesizing new organic compounds is a task which requires excessive amounts of time and has always been valued among chemists. The synthesized compound, P-methylacetophenone, belongs to the ketone functional group because it has the RCOR' arrangement. The mode of reaction of ketones is that they undergo addition reactions such as nucleophilic and electrophilic addition reactions. They are less reactive than aldehydes because of the presence of alkyl (CH3) group(s). They prevent such reactions from happening because of the reduced positive charge. Therefore, it isn't acceptable to expect the compound to react through substitution reactions as these reactions are not typical for ketones. The compound is an aromatic ketone...

...Introduction to Organic ChemistryOrganic chemistry is a specific branch of chemistry, basing off of the study of the element carbon, and its relations to life and the world around it. Sometimes called “life” chemistry because of living things presence of carbon, organic chemistry includes reactions, formulas, and processes, are all based off of carbon chains and its unique properties. Carbon, the element used for most radioactive dating, contains specific properties that help is be on of the building blocks of life. There are various different groups and arrangements of the element carbon, all with their own different properties and structures. Carbon is often a key player in making organic compounds, and understanding... these...

...Question 2-What is the effect of an insoluble impurity, such as sodium sulfate, on the observed melting point of a compound? Insoluble impurities, although very. undesirable, will not affect the melting point. Question 3-Three test tubes, labeled A, B, and C, contain substances with approximately the same melting points. How could you prove the test tubes contain three different chemical compounds? Even if two different compounds have the same melting point, if they are mixed together the melting point of the mixture will be lowered because the compounds are no longer pure. You would take a sample from two of the compounds, X and Y, mix them. If the result of a lowered melting point is present, then the two are different... 2-What is the...

Organic and analytical chemistry

...Organic and Analytical Chemistry Infra-red spectroscopy (IR), Mass Spectrometry (MS), and Nuclear Magnetic Resonance spectroscopy (NMR). are three basic methods that are commonly used for the identification of organic compounds. Each of these techniques measures specific properties of molecules that are unique to the particular compound and can be used to determine the structure of its molecules. Together, the information from MS, IR and NMR can be used to determine the chemical identity and three-dimensional structure of the molecules of an unknown compound. MS provides information about the different component pieces of a molecule according to their masses. IR provides information about the functional groups that are present... was the...

Organic Chemistry Testing Markovnikov's Rule

... Testing Markovnikov’s Rule. Introduction. Markovnokov’s Rule is a common rule that is often used in describing the results of most addition reactions in organic chemistry. This rule was formulated in 1870 by a Russian scientist named Viadimir Vasilevich Markovnikov. The rule states that whenever a protic acid (HX) is added to an alkene, the hydrogen acid (H) becomes attached to the carbon that has less alkyl substituent, whereas the halide (X) group becomes attached to that carbon with increased alkyl substituent. This clearly implies that the atom of hydrogen is added to the carbon possessing a high number of atoms of hydrogen, with the x component being added to the carbon atom with a minimal number of atoms of hydrogen... of the formed...
