What are Colligative properties ?

Actually the word co-ligative itself reveals that (“co” means each other and “ligative” means related) These are the properties which are related to each other. The colligative properties are those properties that depend on the number of solute particles in a solution or a mixture. “These properties don’t depend upon the nature of particles “. Following are the colligative properties:- […]

What are the Characteristics of a lone pair ?

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 pair repel the other bond […]

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 concentration of the nitric acid […]

Is Br2 an ionic or a covalent bond?

Br2  is a homoatomic molecule, a molecule with same kind of atoms. So here the electronegativity of both the atoms is same so the shared pair is equally attracted by the two atoms. There is not a chance of transfer of electrons from one atom to another. And thus they go for sharing of electrons only to satisfy their valencies. […]

Terms related to mass

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 10-24 Molecular mass It is […]
