Aromatic Compounds Aromatic compounds are compounds that belong to a large class of unsaturated chemical compounds that are defined by the presence of one or more planar rings of atoms linked together by covalent bonds. The stability of aromatic compounds is referred to as the aromaticity of the compounds as a result of the delocalization … Read more
Acidic Amino Acids Definition Acidic amino acids are those amino acids that have a carboxylic acid group on their side chains at neutral pH, resulting in acidic properties in the molecule. Acidic amino acids have an additional carboxylic group (COOH) in addition to the one present on the linear chain. These types of amino acids … Read more
Amylose Definition Amylose is a polysaccharide consisting of α-D-glucose units that are linked together by α(1→4) glycosidic bonds. An amylose is an essential form of resistant starch that is more resistant to digestion than other starch molecules. The tightly packed helical structure of the molecule aids in its resistance. The carbon atoms in glucose are … Read more
Alkali Definition Alkali is a basic soluble hydroxide of alkali metals or alkaline earth metals. These are strong bases that share most of the characteristics of bases like the formation of neutral salts with acids and the conversion of red litmus paper into the blue. The term alkali is derived from the Arabic work ‘al … Read more
Aldehyde Definition An aldehyde is a type of organic compound containing the functional group with the structure –CHO, where the carbon double-bonded to oxygen is termed the carbonyl group. Aldehydes are generally formed by the removal of a hydrogen atom from an alcohol compound. The chemical formula of aldehyde is R-CHO where the carbon atom … Read more
Differences between Acid and Base Image Source: Pinterest Basis Acid Base Arrhenius concept An acid is a substance that produces hydrogen ion (H+) as the only positive ion when mixed with water. A base is a substance that produces hydroxyl ion (OH–) as the only negative ion when mixed with water. Bronsted-Lowry Concept An acid … Read more
Cation Definition A cation is an atom or a group of atoms bearing one or more positive electric charges. Cations are formed in various ways, some of which are: When electrons are removed from neutral atoms or ions or other molecules. By the combination of positive ions with other molecules. By rupture of covalent when … Read more
Solute Definition A solute is a substance that is added to a solvent to form a solution. The solute can exist in all three forms of matter as solid, liquid, or gas. In a homogenous mixture, the solute completely dissolves in another substance, and the solute is uniformly distributed throughout the solution. In a heterogeneous … Read more
