Determine if the bonds in the molecule are covalent or ionic. Ionic bonds occur between ions, atoms which have become either negatively or positively charged when their number of electrons are no longer equal to their number of protons. Atoms in such bonds can be considered polar, but only at...
With some chemical knowledge, you can fairly easily guess if a molecule will be polar or not. Each atom will have a different level of electronegativity, or ability to attract electrons. Actually calculating the polarity of a molecule precisely, however, requires determining the shape of the mole...
The principle of solubility, "like dissolves like," emphasizes the importance of polarity in determining whether substances will mix. Polar molecules, such as water and ethanol, dissolve in each other due to their similar net dipoles. Understanding the polarity of various organic compounds,...
Explain how to determine if a molecule is polar including its bond polarity. How can you tell whether a molecule is polar or not? How can knowing both the electron geometry and the molecular geometry assist in determining whether a molecule is polar or nonpolar?
Related to this Question How is the polarity of a ''bond'' different than polarity of a ''molecule''? What makes a particular molecule polar versus non-polar? What is the difference between polar, nonpolar bonds, and how these affect the polarity of a molecule overall?
As mentioned earlier, polar solvents are good at dissolving polar solutes. To explain this, we'll describe the process that occurs when table salt (sodium chloride) dissolves in water. As we learned inThe Mole, water is a polar molecule with partial positive charge on each hydrogen atom and ...
Another aspect that needs to be considered is the intended use conditions for the device. Extractions should be carried out in both a non-polar and polar solvent. Typical non-polar solvents include hexane and chloroform, and typical polar solvents include saline or water. Generally, the solvent...
the more energy will be required to disrupt these bonds when melting or boiling compounds, thus raising the observed temperatures from expected relative to their mass. In addition, hydrogen bonds requirepolarbonds in the molecule and H-Bond Donor proton involved isprotic(a donatable hydrogen atom)...
If the rising temperature affects glaciers and ice shelves, could the polar ice caps be in danger of melting and causing the oceans to rise? We'll look at this danger in the next section. Water Vapor, The Other Greenhouse Gas Water vapor is the most abundant greenhouse gas, but it is ...
