Alkanes, Alkenes, and Alkynes (Hydrocarbons)

In organic chemistry, a hydrocarbon is an organic compound consisting completely of hydrogen and carbon. The carbon atoms combine together to create the framework of the compound, and the hydrogen atoms attach to them in many possible configurations. Hydrocarbons are the primary elements of petroleum and natural gas. They serve as fuels and lubricants as […]

Air pollution: Dust and Wildfire

The alteration in the environment induced by the natural or artificial introduction of dangerous contaminants into the environment, which can result in ecological instability, disturbance, or injury. As a result, pollution is defined as the introduction of poisons into the natural environment, resulting in detrimental changes. Pollution can be biological chemicals or energy, such as

A Simple Note On Properties Of Dioxygen

Diοxygen is a mοlecule that plays an impοrtant rοle in many biοlοgical prοcesses. It is necessary fοr all life. It is fοund in air, water, and, mοst impοrtantly, οn the Earth’s surface. It helps plants grοw and breathe, and it is alsο respοnsible fοr the combustion of fuels in engines. In additiοn, diοxygen is used

A quick notes on causes Sulfurous Smog

“London smog” is another name for the sulphurous hazed (first formed in London). Sulfurous smog is created by the use of sulfur-bearing fossil fuels, mainly coal. In the early twentieth century, the impacts of coal combustion were observed.  Dampness and a high concentration of suspended particulate matter in the air intensify this type of smog.

A brief note on Smog causes

The Smog, also known as smoke fog, is a type of severe air pollution. The term “smog,” which is a contraction (portmanteau) of the words smoke and fog, was coined in the early twentieth century. Because of its opacity and odour, smoky fog is referred to as. The term was originally intended to refer to

Free Radical Mechanism of Halogenation

 Due to the presence of a triple bond in alkynes, halogens, water etc.can be added to them by the process of the addition reaction. A series of actions is required to create additional products. The formation of additional products is attributed to the stability of vinylic cations in the presence of water. Asymmetric alkynes must

The Greenhouse Effect

The greenhouse effect is the mechanism that keeps our planet’s temperature stable. The Earth’s atmosphere functions like the glass panes of a greenhouse, trapping part of the sun’s radiation. Incident radiation energy penetrates the atmosphere, and some is reflected back to the atmosphere from the Earth’s surface as infrared (IR) radiation.  The Earth receives a

Property of Carbon Dioxide

Carbon dioxide is a chemical molecule that occurs naturally and plays an important part in the Earth’s environment. It is required for photosynthesis, which is required for all plants to exist. Carbon dioxide also aids in the regulation of the planet’s and atmosphere’s temperatures. They’re known as greenhouse gases because they let sunlight in but

Preparation Of Acetylene From Calcium Carbide

Acetylene, also known as ethyne, is the most basic and well-known member of the hydrocarbon series containing one or more pairs of carbon atoms linked by triple bonds, also known as the acetylenic series, or alkynes. It is the simplest and best-known member of the hydrocarbon series containing one or more pairs of carbon atoms

Peroxide Effect

Alkenes are unsaturated hydrocarbons, meaning that each alkene molecule has at least one double bond. They demonstrate additional reactions in which an electrophile attacks the carbon-carbon double bond to create extra byproducts attributed to the prevalence of pi electrons. Alkanes are unsaturated hydrocarbons, which means that each molecule of an alkane has at least one
