Alcohols Compounds in which the hydroxyl group (—OH) is linked to aliphatic carbon chain or in the side chain of an organic compound are called alcohols. The alcohols containing one, two or three hydroxyl groups per molecule are called mono, di or trihydric alcohols respectively.Alcohols are further classified as primary (1°), secondary (2°) and tertiary … Read more
Saturated And Unsaturated Hydrocarbons Hydrocarbons, or molecules which contain hydrogen atoms and carbon atoms that are bonded to each other and may or may not contain other atoms, are classified into two distinct categories: saturated and unsaturated. Saturated Hydrocarbons A Saturated hydrocarbon is a hydrocarbon in which all the carbon-carbon bonds are single bonds. A … Read more
Molecules of organic compounds except that of hydrocarbons can be divided into two parts, a reactive part which is referred to as functional group and a skeleton of carbon atoms called alkyl group. The properties of a compound are largely determined by the functional group. Different compounds having same functional group have similar properties and … Read more
There are two types of overlapping orbitals, that is, sigma (σ) and Pi (π). Both bonds are formed from the overlap of two orbitals, one on each atom. Sigma bonds occur when orbitals overlap in an end-to-end fashion, with the electron density concentrated between the nuclei of the bonding atoms also referred to as the … Read more
What Is A Colloid? A colloid is a mixture with particles ranging between 1 and 1000 nanometers in diameter and still able to remain evenly distributed throughout the solution. In colloids the substances remain dispersed and do not settle to the bottom of the container. The colloid particles are generally larger than those in a … Read more
Overview Argon is a chemical element with the symbol (Ar) and atomic number 18. It is in group 18 of the periodic table together with Helium (He), Neon (Ne), Krypton (Kr), Xenon (Xe) and Radon (Rn). They are generally categorized as noble gases. Argon is colorless, odorless, tasteless, nontoxic and nonflammable gas. It is chemically … Read more
Bunsen burner is named after Robert Bunsen, a German chemist who introduced it in 1885. It is a common piece of laboratory equipment that produces a single open gas flame which is used for heating, sterilizing or combustion. The gas can be natural gas or a liquefied petroleum gas such as propane, butane or a … Read more
Overview Bismuth is a chemical element with the symbol Bi and atomic number 83. Bismuth is hard, brittle, lustrous and coarsely crystalline. It can be distinguished from all other metals by its color- gray-white with a reddish tinge. Bismuth is usually mixed with other metals such as lead, tin, iron or cadmium to form low-melting … Read more
Isopropyl bromide also referred to as 2-Bromopropane or 2-propyl bromide, is the halogenated hydrocarbon with the formula CH3CHBrCH3. It is a colorless liquid, insoluble in water but soluble in ethanol and ether. T is used for introducing the isopropyl functional group in organic synthesis. 2-Bromopropane is prepared by heating Isopropanol with hydrobromic acid. Properties Isopropyl … Read more
