It is the reaction between alkyl halides and sodium in the dry ether to give alkanes with higher number of carbon. 2R-X + 2 Na —> R-R +2NaX
It is the number of lattice points touching one lattice point in a crystalline solid. For example in case of Sodium chloride it is 6 .
1. Paramagnetism :- This is the phenomenon by which substances are weekly attracted by the magnetic field. It arises because the substances are magnetized in the same direction of the applied magnetic field. This property is shown by the atom, ions or the molecules that contain unpaired electrons. 2. Ferromagnetism:- This is the phenomenon by
These are the elements that can act as a base as well as an acid. If they react with an acid , they behave as a base . And if they react with a base they behave as an acid . Oxides of aluminum and gallium are amphoteric in nature.
The elements belonging to Group 1 and group 2 of periodic table has the strong tendency to form cations. The reason behind this tendency is that the elements belonging to group 1 and 2 have one and two valance electrons respectively. By loosing the valence electrons, they will aquire noble gas configuration. It is easy
The answer is simple just look at the combustion reaction of the hydrogen and you will get water.
Today me and my friend were out on an evening walk. There we saw an insect with a different look. We wished to have a photo 📷 of that. But as we clicked the first picture he became camera conscious and started moving away from the camera. After a lot of patience we succeeded in
Ald + ol Ald- Aldehyde ; ol – Alcohol. As the name suggests , this is a type of reaction which involve the formation of such a molecule which have “alcohol and aldehyde” functional groups.
The P2 molecule of phosphorus is not found because of the larger size of the phosphorus atom. The phosphorus is so larger that the p-orbitals which are required to overlapp sideways , are unable to overlapp sufficiently to make a pie bond. Below is the structure of oxygen atom that is showing π-bond But phosphorus
What are the characteristics of a lone pair? Characteristics of a lone pair Lone pair are the pair of electrons that do not take part in any chemical bond. They affect the symmetry of molecule or the shape of molecule as they interfere with the other electrons of the molecule . The electrons of lone
What are azetopes? Azeotropes are the constent boiling mixtures or solutions. it means that these mixtures can not be separated by simple distillation or boiling , because they will have the same composition of mixture even in the vapour state. for example as in case of mixture of nitric acid and water, the highest attained
In case of PF3 the size of F is small and thus it approaches near to the central atom that is P. as it approaches near to P there comes the repulsion between the bond pairs, which widens the bond angle and makes it larger than in case of PCl3. Here two types of forces
There is a trick in learning this reaction I will make it very easy for you to learn and rewrite. Firstly see the reaction:- Na2CO3 + 2HCl → 2NaCl + CO2 + H2O Tricks to learn:– Firstly see the formula of carbonate its CO3 , this will be converted into CO2 , One oxygen of
See the ion is a proper charged particle, but dipole is a neutral olecule which is having polarity in it . the dipole is having temporary charge where as the ion is having a permanent charge. Now lets see the cases Case 1 :- Ion – dipole attraction Here a permanent ion is attracting a
In case of ionic compounds we have crystal lattice composed of ions. And there is a never ending pattern of ions and that made it difficult to calculate the molecular mass. Thus we used a simple method by taking the ratio of the ions and then adding their masses, like in case of NaCl ;
Here you can see the hybridization of both is same , both of these two elements have seven electrons in outermost shell and below is the diagram showing the electrons filled in s-subshell and p-subshell . one orbital of s- subshell and three orbitals of p-subshell are used during hybridisation. So the type of hybridization
Chemical bond may be defined as the force of attraction by which two atoms are held together. The chemical bonds lead to the formation of molecules and crystals. There are various kind of bonding that we see around us. Covalent bond A covalent bond is formed by mutual sharing of electrons between two atoms. For
Atomic mass Atomic mass of an element is the relative mass as compared with an atom of carbon 12 and it is expressed in AMU. A.M.U. AMU is the Atomic mass unit and it is defined as the mass equal to 1 by 12th of the mass of carbon 12 isotope. 1 amu = 1.66056x
We come across the various kind of mixtures in our daily life that have different kind of components and sometimes we have to separate the components for our benefit and there comes the need of separation in our day to day life. we do separation by using different kind of separating techniques. some techniques Are
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
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 relate number of molecules with the weight. A mole of a substance is equal to as many molecules of that substance as there are number
