Answer:

synthesis rxn

Explanation:

synthesis reaction

A synthesis reaction OCCURS when two or more reactants COMBINE to form a single PRODUCT. In a decomposition reaction, ONE reactant breaks down into two or more products. This is the REVERSE of a synthesis reaction

Question:

Give the IUPAC Name of the organic compound,

CH₃-C(=O)-CH₂-CH(OH)-CHO

Answer:

The IUPAC Name of the given compound is

Here, in this compound we have 3 functional groups viz.

→ Aldehyde, Alcohol, Ketone.

According to IUPAC convention, Aldehydes and their DERIVATIVES have the highest priority than Ketones and Alcohols.

So in this case the Aldehyde group has the highest priority and therefore makes up the name of the base compound. (-al)

Answer:

Dipole-Dipole interactions occur between polar MOLECULES.  In section 8.8 we learned that polar covalent bonds occur between atoms of different electronegativity (section 8.7), where the more electronegative atom attracts the electrons more than the electropositive atom, and base on the geometry, this may or may not result in a polar molecule.  If the center of positive charge (defined by the nuclei) does not coincide with the center of negative charge (defined by the electron orbitals), the molecule is polar, which is easiest to visualize for nonsymmetric orientations of bonds between atoms of different electronegativities.  That is, a polar molecule with a permanent dipole results if all the bond dipole vectors add to a net dipole.  In this case the molecule's center of positive charge (denoted by δ+) does not coincide with the center of negative charge (denoted by δ-) and the molecular dipole moment (μ

μ

) is this partial charge times the distance between them.  Please review sections 8.7 and 8.8  if needed, and remember that if bond dipoles are of SYMMETRIC ORIENTATION, like in the linear carbon dioxide, they cancel each other and the molecule is non-polar.  So polar bonds can result in non-polar molecules!  You should also note that the center of positive charge need not be where there is a nucleus.  For example, in water, the center of positive charge is half WAY between the two hydrogens.

Figure 11.3.1

11.3.

1

:  Water's dipole moment has a positive center between the two nuclei of the hydrogens.

Although molecules in a liquid are in constant motion, they tend to align in the lowest energy orientation, which would be to maximize attractions (parts a & b of fig. 11.3.1) and minimize repulsion (parts c & d of fig. 11.3.1). This follows the same logic we used for ion-dipole interactions, in that the attractive interactions cause dipoles of opposite charge to be closer, resulting in stronger interactions, while dipoles of like charge tend to be FARTHER apart, resulting in reduced interactions.  Therefore, unlike ion-ion interactions, but like ion-dipole interactions, dipole-dipole are always attractive.

The deposition of particles from SUSPENSION onto solid surfaces is a subject of great significance in many industries. In some cases, deposition is desirable, as in filtration and various processes in which a COATING of deposited particles needs to be FORMED. In many other instances deposition needs to be PREVENTED as far as possible. These include detergency, mineral processing (where ‘slime coating’ of colloidal particles onto larger grains can be a serious problem) and the fouling of heat exchanger surfaces. A number of biological examples could be mentioned, such as the deposition of bacteria on the tooth SURFACE and thrombus formation associated with artificial organs.

SILICON oxide is an ACID oxide. THEREFORE, it dissolves in alkaline solutions.

Acid and acid oxide do not react under normal conditions. Therefore, you do not increase the SOLUBILITY of the silicon oxide in the acid solution.
