Functional Group
In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition. This enables systematic prediction of chemical reactions and behavior of chemical compounds and the design of chemical synthesis. The reactivity of a functional group can be modified by other functional groups nearby. Functional group interconversion can be used in retrosynthetic analysis to plan organic synthesis. A functional group is a group of atoms in a molecule with distinctive chemical properties, regardless of the other atoms in the molecule. The atoms in a functional group are linked to each other and to the rest of the molecule by covalent bonds. For repeating units of polymers, functional groups attach to their nonpolar core of carbon atoms and thus add chemical character to carbon chains. Fun ...

Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Hydroxy Group
In chemistry, a hydroxy or hydroxyl group is a functional group with the chemical formula and composed of one oxygen atom covalently bonded to one hydrogen atom. In organic chemistry, alcohols and carboxylic acids contain one or more hydroxy groups. Both the negatively charged anion , called hydroxide, and the neutral radical , known as the hydroxyl radical, consist of an unbonded hydroxy group. According to IUPAC definitions, the term ''hydroxyl'' refers to the hydroxyl radical () only, while the functional group is called a ''hydroxy group''. Properties Water, alcohols, carboxylic acids, and many other hydroxy-containing compounds can be readily deprotonated due to a large difference between the electronegativity of oxygen (3.5) and that of hydrogen (2.1). Hydroxy-containing compounds engage in intermolecular hydrogen bonding increasing the electrostatic attraction between molecules and thus to higher boiling and melting points than found for compounds that lack this ...

Aluminium Monoacetate
Aluminium monoacetate, also known as dibasic aluminium acetate, and formally named dihydroxy aluminium acetate, is a salt of aluminium with acetic acid. It has the formula Al(OH)2(CH3COO), with aluminium in an oxidation state of +3, and appears under standard conditions as a white solid powder. Chemistry Aluminium monoacetate is prepared from the reaction between Al(OH)3 and dilute aqueous acetic acid. It is also formed from the successive hydrolysis of aluminium triacetate. :Al(CH3COO)3 + H2O → Al(OH)(CH3COO)2 + CH3COOH :Al(OH)(CH3COO)2 + H2O → Al(OH)2(CH3COO) + CH3COOH Uses Aluminium monoacetate is a dermatological agent used as an antiseptic and astringent. It is used as an antiseptic to reduce the possibility of infection in minor wounds, cuts, and burns. Specifically, it treats itching, stinging of the infected skin, inflammation Inflammation (from la, inflammatio) is part of the complex biological response of body tissues to harmful stimuli, such as path ...

Carafate
Sucralfate, sold under various brand names, is a medication used to treat stomach ulcers, gastroesophageal reflux disease (GERD), radiation proctitis, and stomach inflammation and to prevent stress ulcers. Its usefulness in people infected by ''H. pylori'' is limited. It is used by mouth (for upper GIT ulcers) and rectally (for radiation proctitis). Common side effects include constipation. Serious side effects may include bezoar formation and encephalopathy. Use appears to be safe in pregnancy and breastfeeding. How it works is unclear but is believed to involve binding to the ulcer and protecting it from further damage. Sucralfate was approved for medical use in the United States in 1981. It is available as a generic medication. In 2020, it was the 182nd most commonly prescribed medication in the United States, with more than 2million prescriptions. Medical uses Sucralfate is used for the treatment of active duodenal ulcers not related to the use of nonsteroidal anti-in ...

Burow's solution preparations have been diluted and modified with amino acids to make them more palatability, palatable for use as gargles for conditions like aphthous ulcers of the mouth. In veterinary medicine, aluminium triacetate's astringency property is used for t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium Hydroxide
Aluminium hydroxide, Al(OH)3, is found in nature as the mineral gibbsite (also known as hydrargillite) and its three much rarer polymorphs: bayerite, doyleite, and nordstrandite. Aluminium hydroxide is amphoteric, i.e., it has both basic and acidic properties. Closely related are aluminium oxide hydroxide, AlO(OH), and aluminium oxide or alumina (Al2O3), the latter of which is also amphoteric. These compounds together are the major components of the aluminium ore bauxite. Aluminium hydroxide also forms a gelatinous precipitate in water. Structure Al(OH)3 is built up of double layers of hydroxyl groups with aluminium ions occupying two-thirds of the octahedral holes between the two layers. Four polymorphs are recognized. All feature layers of octahedral aluminium hydroxide units, with hydrogen bonds between the layers. The polymorphs differ in terms of the stacking of the layers. All forms of Al(OH)3 crystals are hexagonal : *gibbsite is also known as γ-Al(OH)3 or α-Al(OH) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
