Conductance Behaviour of weak electrolyte: As weak electrolyte dissociates to a much lesser extent than strong electrolyte. For weak electrolyte, there is a very large increase in conductance...

ELECTROCHEMISTRY Chemistry: Physical Chemistry Chapter In mid, 17808 anatomist Luigi Galvani (Italy) was studying effects of atm. electric discharge. One day, in his garden, he fastened bross...

Predicting The Hybrid State of Central Atom The hybrid state of central atoms in simple molecule or in plyatomic ion can be easily predicted by the following considerations : (i) Count the...

1. Formation of boron trifluoride (BF3). Boron (5B) atom has ground state configuration as 1s2 2s2, 2p1. But in the excited state its configuration is 1s2, 2s1, 2px1, 2py1. One 2s-orbital...

(b) Bond Length It has already been discussed that two bonded atoms in a molecule remain held up at a certain distance from each other. They cannot approach too close because it leads to...

5. Effect of Temperature. Formation of a solution may be exothermic or endothermic process and may be represented as follows : Exothermic : Solute + Solve Solution + Heat ....(1) ...

(4) Cation with non-inert gas atom structure _ The cations with the inert gas electron configuration are most effective in shielding the nuclear charge from its surface while the cations with...

(3) Solubility. Alcohols, glycol, glycerol and sugars are soluble in water due to the formation of hydrogen bond with water molecules. Dimethylether, (CH3)2O, is miscible in water as it can...

(ii) Intramolecular hydrogen bonding. When hydrogen bonding exists within the molecule it is called intramolecular hydrogen bonding. In such type of hydrogen bonding two groups of the same...

Chemical Bonding Hydrogen Bond Hydrogen bond is formed when a slightly positive hydrogen atom, attached covalently to strong electronegative atom A (e.g., F, O or N) is held by a...

The above method of writing the electronic configurations is quite cumbersome. Hence, usually the electronic configuration of the atom of any element is simply represented by the...

When l = 0, m = 0, i.e., one value implies that ‘s’ subshell has only one space orientation and hence, it can be arranged in space only in one way along x, yor z axes. Thus,...

Explanation of Black body radiation and Photoelectric effect. Explanation of Black Body Radiation. When some solid substance is heated, the atoms of the substance are set into oscillation and emit...

The de Broglie Relation. The wavelength of the wave associated with any material particle was calculated by analogy with photon as follows:– In case of a photon, if it is assumed to have wave...
