Alkane

Alkane

alkane definition
www.ntsteacher.com
Alkane is also known as organic compounds or paraffin. One alkane compound contain one hydrogen and carbon atoms that are arranged in tree like structure . In alkane, all carbon atoms are single bonded. The general formula of alkane is CnH2n+2. Each carbon atom has our bonds and every hydrogen atom is bonded with carbon atom. Waxes are higher alkanes, in which carbon atoms are greater than 18. Alkanes are less reactive as compared to other alkenes and alkynes. Alkanes are mostly present in mostly natural gas and petroleum.  Alkanes are saturated hydrocarbons which contain only single bond and also known as structural because it contains only maximum numbers of hydrogen atoms. Alkanes compounds show three dimensional shape and covalent bond is present between alkanes compounds. In methane C-H bonds are directed to make tetrahedral structure at the angle of 109 degree. Alaknes does not show reaction with air but in heated form they show slow response in this regard.  Alkanes are used as fuel because, the reactions of alkanes are exothermic.  The chemical properties of alkanes compounds are similar but physical properties are various such as density or boiling point of compounds. Alkanes are also known as homologous.  Alkanes molecules easily make ring or chain like structure.  Alkane can react only in the form of gas for example methane react in the form of natural gas or petroleum.

Characteristics of Alkane

General Formul is CnH2n+2.
      1. Alkanes are present in Natural gas ant Petroleum.
2. Alkanes are Less Reactive
3. Alkanes have Low Melting Point
4. Alkanes are Soft
5. Alkanes are Crystalline in solids.
6. Alkane contain non polar molecules.
7. Alkanes are also less reactive to many laboratory reagents.
8. If the numbers of molecule increases then the melting and boiling points of alkane also increases.
9. Melting point increase due to strong intermolecular forces.If the weight of molecule is higher than the more 10. electrons are present.

Zoology

Zoology The study of animals is known as zoology. The word zoology is derived from a Greek  word’ ’Zion’’ and logos which means knowledge of animals. I n this branch we deals with structure, distribution and classification of animal are studied. History www.ntsteacher.com Conrad Gesner is known as the father of modern zoology. Modern zoology contain the study of animals from ancient to modern times and the role of Aristotle and Galen is very common in the history of zoology. The ancient work of this famous scientist is very important in zoology history. The work of Carl Linnaeus and Buffoon is very important in the diversity of life and the fossil record as well as the development of organisms. In 18 th and 19 th centuries, zoology became professional scientific branch. The interaction between organism and environment was studied by Alexander von Humboldt. Charles Darwin The work of Charles Darwin  Is important in the branch of zoology. The branch em...

Phospholipid Bilayer Structure

Plasma Membrane Plasma membrane is also known as cell membrane. Plasma membrane contain 60 to 80% protein. It contain 20 to 40% lipids and little amount of carbohydrates. Plasma membrane is permeable or selective permeable. Fluid model was most accepted as compared to other models. Functions It play important role in transport of material from inside to outside the body by active transport system which means the movements of material from lower to higher direction by using ATP molecules. Through plasma membrane only small molecules like gas, water or glucose molecules move. It also protect from outer toxic material. Composition It is composed of phospholipids layer that contain Cholesterol which make the membrane fluid consistent and Protein.  Phospholipids composed of glycerol, two fatty acids and a phosphate group.

blue whale challenge

Blue Whale Real Story www.ntsteacher.com The blue whale game is also known as blue whale challenge is an internet game which exist in many countries of the world and it contain 50 tasks which complete in the 50 days period and the last task requiring the player to attempt suicide. This processes of breached whales which is linked to attempt suicide. This game start in 2013 from Russia  F57 which is called death group. A student Philip Budeikin who was expelled from his university statted that his purpose was to clean the sucity by pushing to sucide those he deemand as having no value. In 2016, Russia Blue whale came into boarder use among youngers after a joutnalist brought attention to it through an article that  linked several unrelated sucide victims which was related to the blue whale. In Russia, his founder Budeikin was arrested and pled guilty to inciting at least teenage girls to attempt sucide. Game Bases and Rules This game was based on the relationship bet...
