The strength of an acid depends upon the oxidation state of the central atom. More is the oxidation state higher is the acidic character. In case of HClO4(perchloric acid) the oxidation state of chlorine is +7. And in case of H2SO4 (sulphuric acid) the oxidation state of Sulphur is +6 . The oxidation state of
Actually the hydrogen bond is simply a type of attraction which is caused by the the electronegativity difference between hydrogen and highly electronegative element like oxygen carbon nitrogen and fluorine. Intermolecular hydrogen bonding takes place between two molecules having hydrogen and electronegative element. Hydrogen is attracted by the electronegative element of another molecule for example
The answer to this question is very simple . There are two major reasons behind it. 1. Catenation :- It is the property by which the carbon can make long chains, branched chains and ring or cylic structural by joining with its own atoms. Due to this it can make a variety of molecules. 2.
Chlorobenzene and bromobenzene can be prepared by treating bezenediazonium chloride with cuprous chloride or cuprous bromide. This reaction is also called Sandmeyer’s reaction.
It states that for a solution of volatile components, the partial vapour pressure of each component is directly proportion to the mole fraction of the component in the solution.
1. Schottky defect:- In this kind 9f defect equal number of cations and anions are missing from the crystal lattice. Due to this the vacant sites or the holes are present in the lattice. This kind of defect is present in the ionic compounds with high coordination number and equal size of ions. Density of
There are two types of bonds that can be formed Either by sharing of electrons , that is covalent bond. Or 2. By transfer of electrons , that is ionic bond. Now the question is that , why to go for covalent bond? An important aspect of ionic bond is that the difference of electronegativity
Acid base and salts Acids:- these are the substances that Are sour in taste. Turn blue litmus red. Give H+ ions. Can accept a pair of electrons. Base :- These are the substances that Are bitter in taste. Turn red litmus blue. Soapy in touch. Give OH– ions. How to recognise the acid and bases?
the phenol is more acidic as compared to ortho methyl phenol because the methyl group is electron releasing group which will increase the electron density in the ring as well as on the carbon atom attached to -OH (hydroxyl group) thus -OH group will not release the H+ ion. but in case of phenol there
