Hydrocarbon class 10 & 9 carbon and its compunds

 Hydrocarbons

 

What is a hydrocarbon?

 

*  In organic chemistry, a hydrocarbon is a compound consisting primarily of

carbon and hydrogen along with other elements added on as functional groups

Few examples of Hydrocarbons are

*Methane

*Ethane

*Ethanol

*Propane

*Butane

Types of hydrocarbons:

*The hydrocarbons can be classified as

*Open chain or acyclic hydrocarbons

*Cyclic hydrocarbons

*Acyclic hydrocarbons have a linear structure and do not form rings

*Cyclic hydrocarbons have a structure like a ring

Acyclic Hydrocarbons:

* Organic compounds in which all the carbon atoms are linked to one another to form an open chain are called Acyclic Hydrocarbons.

*These can be saturated or unsaturated

Saturated Hydrocarbons:

*The Hydrocarbons where the carbon atoms are linked by only single bonds are called saturated Hydrocarbons.

*They are also alkanes and parrafins

Unsaturated Hydrocarbons

* The carbon atoms are connected by double or triple bonds

*They are alkenes or alkynes.

Structural isomers

*Before moving on to see the structures of few hydrocarbons we need to understand what an isomer is?

* A structural isomer, or constitutional isomer (per IUPAC[1]), is a type of  isomer in which molecules with the same molecular formula have different  bonding patterns and atomic organization, as opposed to stereoisomers, in  which molecular bonds are always in the same order and only spatial arrangement differs.

*In chain isomerism, or skeletal isomerism, components of the (usual carbon)  skeleton are distinctly re-ordered to create different structures. Pentane  exists as three isomers: n-pentane (often called simply "pentane"), isopentane  (2-methyl butane), and neopentane (dimethylpropane)


Nomenclature of Organic compounds  (IUPAC Names):

Organic Compounds are named as

* Root word

    * Suffix

              *Primary Suffix

*Secondary Suffix

* Prefix

* Primary Prefix

* Secondary Prefix



Root Word

* It is the basic unit of the word

* It is based on the number of carbons present

 

Prefix

*A primary prefix  Cyclo- is used to distinguish cyclic from acyclic compounds

Uses of Hydrocarbons:

* Natural gas and fuels - Many of the natural fuel sources we use are hydrocarbons. Compounds like methane, butane, propane, and hexane are all hydrocarbons. Their chemical formulas consist of only carbon and hydrogen atoms, in a variety of ratios and chemical configurations.

* Plastics - Many of the plastics we use in everyday life and in the industry are made from long chains of monomers, formed from petrochemicals. These petrochemicals are simply hydrocarbons of different chemical compositions.

* Paraffin - The wax that we use for a variety of industries, everything from candle making and food preservation to medical and industrial uses, contains hydrocarbons.

* Isopropyl alcohol - This common medical chemical is interesting in that it contains a hydrocarbon that is then bonded to further carbon atoms. The initial hydrocarbon, CH3, bonds to other atoms to form (CH3)2CHOH.

* Asphalt - the common substance that most people are familiar with is actually a hydrocarbon that has been heated to form the substance tar. It is then mixed with other key industrial ingredients to form the mixture that makes up the road's surface.

Chemical Kinetics class 12

Chemical Kinetics  name of the chapter: Chemical Kinetics Content Provider: FIITJEE Lecturer from FIITJEE Introduction based on NCERT: Chemistry, by its very nature, is concerned with change. Substances with well-defined properties are converted by chemical reactions into other substances with different properties. For any chemical reaction, chemists try to find out (a) the feasibility of a chemical reaction which can be predicted by thermodynamics ( as you know that a reaction with ΔG < 0, at constant temperature and pressure is feasible); (b) the extent to which a reaction will proceed can be determined from chemical equilibrium; (c) speed of a reaction i.e. time taken by a reaction to reach equilibrium. Along with feasibility and extent, it is equally important to know the rate and the factors controlling the rate of a chemical reaction for its complete understanding. For example, which parameters determine how rapidly food gets spoiled? How to design a rapid...

Periodic Table Shortcut

 Periodic table shortcut  Name of the page:   shortcut for periodic table  Done by:                       FIITJEE Student Applicable for all the classes  What is a Periodic Table? a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns. The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. who invented the periodic table? many collections of scientists invented it. Embedded PDF:

Solid state class 12 Physical

 Solid states  name of the chapter:  Solid State Content Provider: FIITJEE Lecturer from FIITJEE Introduction given by NcertText book:  We are mostly surrounded by solids and we use them more often than liquids and gases. For different applications, we need solids with widely different properties. These properties depend upon the nature of constituent particles and the binding forces operating between them. Therefore, the study of the structure of solids is important. The correlation between structure and properties helps in discovering new solid materials with desired properties like high-temperature superconductors, magnetic materials, biodegradable polymers for packaging, biocompliant solids for surgical implants, etc. From our earlier studies, we know that liquids and gases are called fluids because of their ability to flow. The fluidity in both of these states is due to the fact that the molecules are free to move about. On the contrary, the constitu...
