Physical adsorption, also known as physisorption, is a reversible phenomenon involving weak Van der Waals forces between adsorbate and adsorbent, whereas chemisorption is an irreversible phenomenon involving strong chemical interaction between adsorbate and adsorbent. S.N Physisorption Chemisorption 1. It is … Read more
The series of elements or ions in the increasing order of reduction potential or decreasing order of oxidation potential is known as the electrochemical series. From the electrochemical series, we can predict the feasibility of the reaction, the emf of … Read more
Nuclear reactions are the process in which two atomic nuclei or one atomic nucleus and a subatomic particle (such as a proton or neutron or high energy electron) collide to form one or more nuclides different from parent nuclei. In … Read more
Radioactivity is the phenomenon of spontaneous disintegration of certain nuclei into other elements with the emission of invisible active radiations. It is a natural phenomenon in which unstable atoms emit radiation to achieve stability. Discovery In 1896 Henri Becquerel discovered … Read more
In any compound, intermolecular forces of attraction and thermal force operate in opposite directions. The intermolecular force of attraction tends to keep the particles together while the thermal force tends to keep the particles apart. The extent of these forces … Read more
Cholesterol is the most abundant sterol in tissues and plasma. It is present in animal or human cells either in free or stored or combined form as cholesteryl ester. It is the fat-like waxy substance that is obtained from the … Read more
Organosilicon compounds are organometallic compounds that contain Si-C bonds. As the Si-C bond is extremely hard and stable, many organosilicon compounds containing Si-C have been synthesized. However, silicon has little tendency to form a bond with itself and does not … Read more
An aromatic nucleophilic substitution reaction is the replacement of hydrogen or substituent on an aromatic ring by a nucleophile. Aromatic rings do not undergo the aromatic nucleophilic substitution reaction under ordinary conditions. The reason for this low reactivity of the … Read more
Coordination compounds are complex compounds consisting of a central metal atom surrounded by nonmetal atoms or groups of atoms called ligands that are chemically linked to it. E.g., Â [Co(NH3)6]Cl3, [CoCl(NH3)5]Cl2 Isomerism in Coordination compounds Isomers are compounds that have the … Read more
