Sodium Thiosulphate is an inorganic salt with the chemical formula Na2S2O3. It is a white colorless crystal or even powder. When degraded into sulfide and sulfate in the air, the material is known to be alkaline. Sodium thiosulphate is soluble in water, producing … Read more
Perchloric acid is the chemical name for chlorine oxoacid. It is also known as hydroxidotrioxidochlorine or hyperchloric acid (HClO4). Acid is a transparent, colorless, and odorless aqueous solution with a concentration ranging from 50% to 72%. It corrodes metals and … Read more
Chemotherapy is one of the most widely used and effective cancer treatments. It kills rapidly developing cells, such as cancer cells, and prevents them from proliferating. Chemotherapy medications may be administered differently depending on the type of cancer and the … Read more
Silicon carbide is a compound of silicon and carbon. It is also known as Carborundum. Edward Acheson of Pennsylvania discovered silicon carbide in 1891. Because of its excellent combination of physical and electrical features, silicon carbide (SiC) is a wide … Read more
mCPBA (Meta-chloroperoxybenzoic acid ) is a peroxycarboxylic acid with the chemical formula C7O3H5Cl. It is a white crystalline powder with a melting point of 90 degrees Celsius. mCPBA is a powerful oxidising agent that is commonly employed as an oxidant … Read more
PCC (Pyridinium chlorochromate) is an oxidizing agent with the formula [C5H5NH]+[CrO3Cl]. It is a reagent in chemical synthesis that is mostly used to oxidize alcohols to generate carbonyls. Corey and associates first developed pyridinium chlorochromate, which is a stable orange solid … Read more
Meta directors are deactivating groups on benzene that direct the electrophile E to the meta position. In comparison to hydrogen, deactivating groups slow down the rate of electrophilic aromatic substitution. Substituents that pull electron density away from nearby carbocations (e.g., CF3, … Read more
Imine is a chemical molecule with a carbon-nitrogen double bond (C=N). They have a C=N link rather than a C=O bond, and are the nitrogen analogs of aldehydes and ketones. So they are compounds with a carbon-nitrogen double bond – … Read more
ortho para directors are electron donating groups on benzene that direct the electrophile E to the ortho- (1,2) and para- (1,4) positions. They are also known as ring-activating groups. For example, when aniline is chlorinated, the resulting products are ortho … Read more
