Everything about chemistry

Acid : It is a substance (compound ) which Gives H+ ions in the solution. We can classify acid in following categories. 1) organic acids 2) inorganic acids. 3)strong acid 4) weak acid 1) organic acids : These are carbon containing acids . e.g carboxylic acid ( - COOH), citric acid (C6H8O7)  , latic acid (C3H6O6), Oxalic acid (C2H2O4). 2) Inorganic acid : The acids which does not contain carbon. e.g.  H2SO4( sulphuric acid) , NH3 ( Nitric acid ), HCl etc. 3) strong acid : The acid which completely dissociates in solution is called strong acid. e.g.HCL , H2SO4, HNO3. 4)weak acid : The acid which does not completely dissolved ( dissociates) In solutions are called weak acid. e.g. acetic acid ( CH3COOH ), latic acid ( C3H6O6), citric acid ( C6H8O7).. I think these are the basic things which we should know about acids. You can buy this book. By using below link. General knowledge book -2021 https://amzn.to/2PDvug1

Chemical bond :- a bond between two atoms is formed when there is sharing of electrons or gain/loss  to form a stable compounds. Type of chemical bonds : 1) covalent bond : it is formed when there is sharing of electrons between two atoms. Also known as π-π bond . ( Lateral overlap) E.g -CH4 , CO. 2) coordinate- covalent bond : It is formed when there is sharing of lone pair of electrons between non-metal to metal. E.g-.  Comples 3) ionic bond : it is formed by gain or loss of electrons between two atoms . Also known as  sigam bond ( axial overlap). E.g -. NaCl. 4) Hydrogen bonds : it is formed due to polarity between two atoms . It is weak bond . It is formed between hydrogen & electronagative atom of another compound. a) intermolecular hydrogen bonding : it is weak bond formed between hydrogen & electronegative atom of another compound. e.g. H2O,NH3. b) intermolecular hydrogen bonding: it is formed within same molecule between hydrogen & electronegative

Definition: The branch of chemistry which deals with study of carbon & carbon related compounds is known as organic chemistry. When reactant gets converted into product between that the reactive intermediate are formed. 1) carbonations : The spaces carrying positive charge on carbon atom and having only 6 electrons in its outer valence shell are known as carbonations. 2) carbanions :- the species carrying negative charge on carbon atom and having 8 electrons in its outer valency are known as carbanions 3) free radicals :- an atom having odd number of electrons is known as free radicals. 4) carbens :-   carbens are neutral, divalent carbon intermediates in which carbon is covalently bonded  to two atoms and has two non bonding orbitals containing two electrons between them . this are  electron deficient species. 5) Arynes or Benzynes :  it is a neutral highly reactive intermediate in which the aromatic character has not been much more and disturbed. 6) Nitrenes : Nitr

What is nanotechnology? Nanotechnology deals with the material having size in the nanometres. If we consider  study of any metal at nano level we find change in the properties of that metal. e.g. colour ,electroconductivity  Case-1 :  If consider gold ( Au - aurum -79) it has yellowish colour by naked eyes. If  we divided the gold in number of parts then its solution will give different colours like blue, red, green , sky blue etc.  Case - 2 : If consider altropes of carbon diamond , graphite , fullerene .  A single layer of graphite will give us graphene which has totally different properties than graphite. Means  if we go at nano level of any material properties are going to change . Some expectional cases are always there. Spary pyrolysis. It is instruments with the help of that we can make different nanomaterials. For intersting facts like this please visit my blog daily, subscribe & follow.

A  rose  is a woody  perennial   flowering plant  of the  genus   Rosa , in the family  Rosaceae , or the flower it bears. There are over 300   species  and  thousands  of  cultivars . They form a group of plants that can be erect shrubs, climbing, or trailing, with stems that are often armed with sharp  prickles . Types of 🌹 :Rosa  containing all  the other roses. This subgenus is subdivided into 11 sections. Banksianae   – white and yellow flowered roses from  China . Bracteatae   – three species, two from  China  and one from  India . Caninae   – pink and white flowered species from  Asia ,  Europe  and  North Africa . Carolinae   – white, pink, and bright pink flowered species all from  North America . Chinensis   – white, pink, yellow, red and mixed-color roses from  China  and  Burma . Gallicanae   – pink to crimson and striped flowered roses from western  Asia  and  Europe . Gymnocarpae   – one species in western North America ( Rosa gymnocarpa ), others in east As
