Chemistry Question & Answer Session

Hello Students,
Do you know ----

Q: Why are the atomic orbitals of oxygen atom in the molecular orbital diagram of carbon monoxide, CO, lower than those of carbon?
A: It is because the electronegativity of oxygen is larger than that of carbon.

Q: Which halogen has the largest oxidizing power?
A: Since the reduction potential of fluorine is the highest, its oxidizing power is the largest.

Q: Describe the numerical tendency of electronegativities of the elements in the periodic table.
A: They increase toward the right and decrease down the table. Namely, the electronegativity of alkali metal Cs is the smallest and that of fluorine F is the largest.

Do you know the kinetic theory of ideal gases???

The kinetic theory of gases explains the macroscopic properties of gases like volume, pressure, and temperature, as well as transport properties such as viscosity , thermal conductivity and mass diffusivity . The theory for ideal gases makes assumptions like --- · The gas consists of very small particles known as molecules. This smallness of their size is such that the total volume of the individual gas molecules added up is negligible compared to the volume of the smallest open ball containing all the molecules. This is equivalent to stating that the average distance separating the gas particles is large compared to their size . · These particles have the same mass . · The ...

Do you know about the Valence Bond Theory !!!

Do you k now a bout the Valence Bond Theory !!! Actully this theory describes a covalent bond as the overlap of half-filled atomic orbitals (each containing a single electron) that yield a pair of electrons shared between the two bonded atoms. We say that orbitals on two different atoms overlap when a portion of one orbital and a portion of a second orbital occupy the same region of space. According to valence bond theory, a covalent bond results when two conditions are met: (1) an orbital on one atom overlaps an orbital on a second atom (2) the single electrons in each orbital combine to form an electron pair. The mutual attraction between this negatively charged electron pair and the two atoms’ positively charged nuclei serves to physically link the two atoms through a force we define as a covalent bond. The strength of a covalent bond depends on the extent of overlap of the orbitals involved. Orbitals that overlap extensively form bonds that are st...

Do you know about the "Hydrogen Bonding" !!!!

Hello Stude nts, Do you know about the "Hydrogen Bonding" !!!! The very large difference in electronegativity between the H atom and the atom to which it is bonded combined with the very small size of a H atom and the relatively small sizes of F, O, or N atoms, leads to highly concentrated partial charges with these atoms. Molecules with F-H, O-H, or N-H moieties are very strongly attracted to similar moieties in nearby molecules, a particularly strong type of dipole-dipole attraction called hydrogen bonding. Examples of hydrogen bonds include HF…HF, H2O…HOH, and H3N…HNH2, in which the hydrogen bonds are denoted by dots. Hydrogen bonds are much weaker than covalent bonds, only about 5 to 10% as strong, but are generally much stronger than other dipole-dipole attractions and dispersion forces. For example : consider the trends in boiling points for the binary hydrides of group 15 (NH3, PH3, AsH3, and SbH3), group 16 hydrides (H2O, H2S, H2Se, and H2Te), and group 1...
