## Physical and Chemical Properties of Alcohols

Updated on 23-Jan-2023 16:43:33
Introduction The organic compounds that form a series that consists of the same functional groups but have variations in their $\mathrm{-CH_2}$ group are determined as the homologous series. In this homologous series, various successive compounds can be seen including alcohol, phenol, ether, and so on. The alcohols have more than one functional group that is quite similar to the functional groups of phenols and ether. Alcohol The organic compound in which the atom of hydrogen or the aliphatic carbon gets replaced by the hydroxyl group is referred to as the alcohols. The compound can be identified by its sweet smell. ... Read More

## Allotropic Forms of Phosphorous

Updated on 23-Jan-2023 15:00:47
Introduction The allotropes of phosphorus are found in different allotropic forms. The main allotropes of phosphorus include the white phosphorus, red phosphorus and black phosphorus. In addition to this, there is also the existence of violet phosphorus. The black phosphorus is black in colour while the white phosphorus bears yellowish colour and red phosphorus has red colour. Allotropes of Phosphorus Allotropy is called the science of occurrence of an element in multiple or more than one physical shape. Here allotropes refer to different types of physical shapes of the same element. It is seen that allotropes is the property of ... Read More

## Photochemical Smog

Updated on 23-Jan-2023 16:15:17
Introduction Photochemical smog is also famous as summer smog and it is very harmful. It is produced when UV light originating from the sun interacts with the oxides of nitrogen. This smog is usually personified as a brown haze in the atmosphere. It is seen in the highly populated cities that are placed in relatively warm climates. It is most see-able during afternoons as well as mornings. What is Smog? The modern world is delivering a hundred tons of waste every hour. Humans are mainly spoiling the rivers, the sea, and even the forest. All of these factors lead to ... Read More

## Photochemical Reaction

Updated on 23-Jan-2023 16:11:05
Introduction The Photochemical Reaction is quite different from a dark reaction, as, in a dark reaction, the thermal reaction concerns the ground state of electrons present within the molecule of a chemical compound. The Photochemical Reaction is responsible for playing a crucial role in defining the nature of chemical species. The chemical species include pollutant species present within the atmosphere. However, the Photochemical Reaction takes place due to the solar radiation within the atmosphere. Defining Photochemical Reaction Photochemical Reaction is nothing but a chemical reaction that takes place when triggered by light radiation from a light source. This results ... Read More

## Phosphorylation

Updated on 23-Jan-2023 16:00:27
Introduction Phosphorylation can be assumed as one of the essential reactions of biochemical in which the molecules of phosphate are added to some organic mixture with the desire of making it functional for several positions in a living being. Another corresponding word is phosphorylate, which also represents the opening of a phosphoryl group into an organic compound. What is Phosphorylation? Phosphorylation is one of the significant reactions which even have significance in biology due to various biological procedures depending on the reactions like apoptosis, proliferation, and regulation of metabolism, inflammation, and subcellular trafficking. In addition to this, phosphorylation in biology ... Read More

## Phosphorus Trichloride

Updated on 23-Jan-2023 15:31:50
Introduction Phosphorus trichloride is considered a fuming liquid and the chemical formula of this element is $\mathrm{PCI_3}$. A colourless liquid is like transparent liquidity in terms of motile. This chemical element is mainly manufactured with the help of burning molten white phosphorus that is kelp in the contact with a strong base of nitrous acid. What is Phosphorus Trichloride? Phosphorus trichloride is mainly available in a liquid state and it can be poisonous as well as volatile in terms of atmosphere. The reactive power of this chemical agent is very high and it displays its explosive nature during the ... Read More

## Phosphorus Pentachloride

Updated on 23-Jan-2023 15:17:39
Introduction Phosphorus Pentachloride can be generated through an effective and common procedure of dry chlorine gas action on phosphorus trichloride. In the solid-state Phosphorus Pentachloride, remain as $\mathrm{PCl_4PCl_4^+ PCl_6PCl_6^-}$. The boiling point of Phosphorus Pentachloride is nearly 166.8°C and the melting point of Phosphorus Pentachloride is about 160.5°C. Phosphorus Pentachloride Phosphorus Pentachloride has a crystalline salt-like structure that gets dissociates partially in solution mainly in polar solvents like nitrobenzene. Phosphorus Pentachloride is determined as the solid having a pale greenish-yellow colour, which can be specified with the formula PCl5. The preparation methods of the Phosphorus pentachloride depict that the ... Read More

## Mechanical Properties of Fluids

Updated on 12-Jan-2023 18:19:20
Introduction The mechanical properties of fluids are a branch of physics that states about the mechanics of the fluids, it includes the liquid, gas and the plasmas. Fluids are incompressible which means the density of the liquid is not dependent on the variation in the pressure and remains as constant. They also count as the most non-viscous. It means, that two liquid surfaces that came in contact are not pressing any kind of tangential force on one another. What is Fluid? In the field of chemistry, the term fluid can be referred to any liquid or ... Read More

## Measurement of Enthalpy and Internal Energy Change

Updated on 16-Jan-2023 11:20:55
Introduction Normally, the measurement of enthalpy and internal energy change is carried out by an experimental approach. This approach is known as calorimetry which is an important part of chemistry. It is mainly a technique which is developed on thermometric procedures. Here, a calorimeter is the vessel in which the procedure happens. In this part, the vessel is submerged in a known liquid volume. What is Enthalpy? Enthalpy is the heat energy and it is absorbed during a chemical reaction progression. In this part, enthalpy is represented by H and it indicates the energy amount. The change ... Read More
