The reaction between an acid and base to give salt and water is called neutralisation reaction. here in the following reaction we can easily see how Hydrochloric acid is reacting with sodium chloride NaOH + HCl ———> NaCl + H2O the nature of salt formed is dependent on the type of acid or base , if there is any difference then […]
Thomson’s model of an atom Thomson proposed the model of an atom to be similar to that of the Christmas pudding. Thomson proposed that An atom consists of a positively […]
Distillation is a type of separating process in which two miscible liquids are separated from each other by using their different boiling points. the one with lower boiling point , […]
Valency :- “It is the combining capacity of an atom”. it also indicates the number of electrons that can be gained , lost or shared . It decides that how […]
The word mole means pile up . This concept originated from a simple problem that was faced by the scientists to calculate the reactions. they needed a concept that could […]
IN CASE OF TOLUENE the methyl group attached to the ring, increases the electron density at ortho and para positions by resonance without changing anything at the meta position. Thus […]
THE ANSWER CAN BE UNDERSTOOD EASILY BY LOOKING AT THE FOLLOWING POINTS:- 1. In case of alcohol the Oxygen atom is joined to the alkyl group on one side and […]
it is a very common question and common example too. i would love to answer. Most people say it is the bond formed due to the transfer of electrons, but this explanstion is not complete. Ionic bond is the bond formed due to strong electrostatic forces of attraction between two oppositely charged ions. here is the complete reaction that takes […]
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 […]
Human digestive system includes two basic things Alimentary canal 2. Digestive glands 1 Alimentary canal : human alimentary canal is basically a pipe of varying diameter which is designed for […]
Lets look from a different angle corrosion is basically oxidation and in oxidation the electrons are lost. Here we have zinc coated on iron being more reactive the zinc will tend to loose the electrons even if the iron is exposed, even then being good conductor the electrons are given to the iron by the zinc. So actually the lost […]
Electron affinity is the amount of energy change during the addition of an electron to an isolated gaseous atom. It can be positive as well as negative. Negative electron affinity means that the energy is released during the addition of electron. Which is a favorable condition for gaining an electron. But positive value means that we have to supply the […]
