Coordination Compounds [NCERT Notes]
Coordination compound. Coordination compound, any of a class of substances with chemical structures in which a central metal atom is surrounded by nonmetal atoms or groups of atoms, called ligands, joined to it by chemical bonds.
General Principles and Processes of Isolation of Elements
A few elements like carbon, sulphur, gold and noble gases, occur in free state while others in combined forms in the earth's crust. The extraction and isolation of an element from its combined form involves various principles of chemistry. A particular element may occur in a variety of compounds.
Alcohols, Phenols and Ethers (NCERT Notes)
Alcohol is the product we get when a saturated carbon atom bonds to a hydroxyl (-OH) group. Phenol is what we get when the -OH group replaces the hydrogen atom in benzene. Ether is the product that we get when an oxygen atom bonds to two alkyl or aryl groups.
Chemical Kinetics (NCERT Notes)
Chemical kinetics is an important phenomenon in physical chemistry. The term kinetics is referred to as the study of motion. ... It is a study of chemical reaction with respect to reaction rates, effect of different variables such as temperature and concentration.
The D and F Block Elements
The d-block elements are called transition metals and have valence electrons in d orbital's. The f-block elements,found in the two rows at the bottom of the periodic table, are called inner transition metals and have valence electrons in the f-orbital's.
P-Block Elements {NCERT NOTES}
The p-block elements are found on the right side of the periodic table. They include the boron, carbon, nitrogen, oxygen and flourine families in addition to the noble gases. The noble gases have full p-orbital's and are nonreactive. p block orbital.
Electrochemistry (NCERT Notes)
Electrochemistry is the study of chemical processes that cause electrons to move. This movement of electrons is called electricity, which can be generated by movements of electrons from one element to another in a reaction known as an oxidation-reduction ("redox") reaction.
Surface Chemistry (NCERT Notes)
Surface chemistry is important in many critical chemical processes, such as enzymatic reactions at biological interfaces found in cell walls and membranes, in electronics at the surfaces and interfaces of microchips used in computers, and the heterogeneous catalysts found in the catalytic converter used for cleaning ...
Haloalkane and Haloarene NCERT Notes
Haloalkanes and Haloarenes Haloalkanes and Haloarenes. Page 1. The replacement of hydrogen atom(s) in a hydrocarbon, aliphatic or aromatic, by halogen atom(s) results in the formation of alkyl halide (haloalkane) and aryl halide (haloarene), respectively.
Aldehydes, Ketones and Carboxylic Acids
Ethers are compounds with an oxygen atom bonded to two alkyl groups. Aldehydes and ketones contain the carbonyl functional group. In an aldehyde, the carbonyl is at the end of a carbon chain, while in a ketone, it is in the middle. A carboxylic acid contains the carboxyl functional group.
Polymers NCERT Notes (12th Class)
A polymer is a molecule, made from joining together many small molecules called monomers. The word "polymer" can be broken down into "poly" (meaning "many" in Greek) and "mer" (meaning "unit"). ... Proteins have polypeptide molecules, which are natural polymers made from various amino acid monomer units.
