What Is Allyl? An allyl in organic chemistry is a substituent functional group with a general molecular formula RCH2CH=CH2. Allyl group holds three carbon atoms and five hydrogen atoms, which gets attached to any other group of atoms through –CH2 group. Allyl group consists of (-CH2-) methylene bridge and is attached with (-CH=CH2) vinyl group. … Read more
What Is Hard Iron? Hard iron is an iron which is not readily magnetized by induction but which retains a high percentage of the magnetism acquired. When a bar of non-magnetized iron is placed in magnetic field, the direction of magnetization of the magnetic domains tends to move towards the direction of the field. This … Read more
Molecular geometry in chemistry is the three-dimensional arrangement of atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths, bond angles, torsional angles and any other geometrical parameters that determine the position of each atom. Understanding the molecular structure of a compound can help determine the polarity, … Read more
What Is Chemical Change? A chemical change happens when one chemical substance is transformed into one or more different substances such as when ion becomes rust. Chemical changes occur throughout the process of chemical reactions and the resulting substances have different properties because their atoms and molecules are arranged differently. Chemists categorize chemical changes into … Read more
Variations, the small differences that exist between individuals can be described as being either discontinuous or continuous. What Is Continuous Variations? In continuous variation, there is a complete range of measurements from one extreme to the other. Human height is an example of continuous variation. It ranges from that of the shortest person to the … Read more
Genotype and phenotype are two fundamental terms in the science of genetics used to explicate the appearance, function and behavior of an organism. The two terms are often used at the same time to describe the same organism but there is a big difference between. The phenotype is the result of genetic factors, environmental influences … Read more
Chromatography is a laboratory technique for separation of mixtures. The mixture is dissolved in a fluid referred to as the mobile phase, which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds, causing them to separate. Chromatography was invented by the Russian … Read more
What Are Biotic Factors? Biotic factors also referred to as biotic components can be described as any living component that affects another organism or shapes the ecosystem. This includes other organisms within their ecosystem and the organism that is being consumed. Biotic factors include animals, plants, fungi, bacteria and protists. Biotic factors also include human … Read more
Trichomes Trichomes is the term used to refer to tiny outgrowths from the plant epidermis. Although the term ‘’Trichomes’’ generally refers to outgrowth ranging from small hairs to larger outgrowths like thorns, it is typically used to refer to the tiny hairs that can be seen emerging from the surface of leaves and other epidermal … Read more
Endpoint And Equivalence Point Titration measures the concentration of an unknown solution that reacts with a solution of known concentration. The process is often used to check the purity of synthesized chemical compounds such as pharmaceuticals. The ideal point for completion of titration is known as the equivalence point. The end point demonstrates the equivalence … Read more
