    *Stereochemistry* is the study of how molecules are affected by the way their atoms are arranged in space. It is also known as 3D chemistry as the word stereo means three dimensional. Using stereochemistry, chemists can work out the relationships between different molecules that are made up from the same atoms

    Stereochemistry is the systematic presentation of a specific field of science and technology traditionally requires a short preliminary excursion into history. Stereochemistry is the ‘chemistry of space ‘, that is stereochemistry deals with the spatial arrangements of atoms and groups in a molecule.

    Buffer solution

    They are those solutions which has a constant value of pH , no matter what we add in  to them .

    Example: The pH of Blood is 7.4-7.6. Blood act as a buffer. As u all know, in spite of eating so many types of food items, the pH of blood remains same.

    The buffer solution is defined as: A solution which resists the change in hydrogen ion concentration on addition of a small amount of acid or a base in to it.

    A solution that only changes slightly when an acid or a base is added to it. For an acid -buffer solution, it consists of a week acid and it's conjugate base . For a base buffer solution,it consists of a week base and it's conjugate acid. ??

    A polar covalent bond exists when atoms with different electronegativities share electrons in a covalent bond. Consider the hydrogen chloride (HCl) molecule. Each atom in HCl requires one more electron to form an inert gas electron configuration.

    polar covalent bonding is a type of chemical bond where a pair of electrons are unequally shared between two atoms. The bonding of hydrogen and chlorine atom leans more tiwards cl atom because cl is more elecronegative in nature than the hydrogen.

    Resonance

    It is given by Heisenberg.

    He took a molecule of ozone. Its structure was represented as:

    According to the structure, it is clearly seen that it has one double bond and another single bond. So, obviously the bond lengths will be different. For double bond between oxygen atoms, the bond length is 121pm and for single bond it is 148pm.

    But, the bond length was found experimentally to be same for both the bonds that is 128pm .This bond length lies in between the values of single and double bond lengths.

    Hydrogen bonding, interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons; such a bond is weaker than an ionic bond or covalent bond but stronger than van der Waals forces.

    0Thank You

    Yogita Ingle 4 years ago

    Hydrogen bonding refers to the formation of Hydrogen bonds, which are a special class of attractive intermolecular forces that arise due to the dipole-dipole interaction between a hydrogen atom that is bonded to a highly electronegative atom and another highly electronegative atom while lies in the vicinity of the hydrogen atom. For example, in water molecules (H2O), hydrogen is covalently bonded to the more electronegative oxygen atom. Therefore, hydrogen bonding arises in water molecules due to the dipole-dipole interactions between the hydrogen atom of one water molecule and the oxygen atom of another H2O molecule.

    The covalent radius, rcov, is a measure of the size of an atom that forms part of one covalent bond. It is usually measured either in picometres or angstroms, with 1 Å = 100 pm. In principle, the sum of the two covalent radii should equal the covalent bond length between two atoms, R = r(A) + r(B).

    The electrons in a covalent bond between two different atoms (H and Cl in this case) are not equally shared by the atoms. This is due to the electronegativity difference between the two atoms. The more electronegative atom (Cl) has greater share of the electrons than the less electronegative atom (H).

    Pyrophosphoric acid, also known as diphosphoric acid, is the inorganic compound with the formula H₄P₂O₇ or, more descriptively, [(HO)₂P]₂O. Colorless and odorless, it is soluble in water, diethyl ether, and ethyl alcohol. Hypophosphoric acid is a mineral acid with the formula H4P2O6, with phosphorus in a formal oxidation state of +4. In the solid state it is present as the dihydrate, H4P2O6·2H2O. In hypophosphoric acid the phosphorus atoms are identical and joined directly with a P−P bond.
