Why do polar molecules have a higher boiling point than non-polar molecules? What is a polar body? Why do we say that a molecule of water is polar? What is the state fish of Alaska? If given a chemical formula, how can do you determine if it is polar or non-polar to determine wha...
Why do ions and polar molecules pass slowly through the bilayer? Why can nonpolar molecules freely cross the cell membrane? Why can hydrophobic molecules cross the cell membrane? What prevents polar molecules from passing through a membrane? Why can't small hydrophilic molecules cross the ce...
In polar molecules, the centers of the positive and negative charges are separated even in the absence of an external electric field. They have a permanent dipole moment. The net dipole moment is zero in the absence of an external electric field. exam

charged. Charged groups may be cationic (positively charged), such as the ammonium group (RNH3+). Other charged groups are anionic, such as carboxylates (RCO2−), phosphates (RPO42-), sulfates (RSO4−), and sulfonates (RSO3−). Examples of polar, uncharged groups include alcohols....
aA typical biomembrane is assembled from phosphoglycerides, sphingolipids, and steroids. All three classes of lipids are amphipathic molecules having a polar (hydrophilic) head group and hydrophobic tail. The hydrophobic effect and vander Waals interactions, discussed in Chapter 2, cause the tail group...
500 degrees Fahrenheit. This intense heat is primarily due to the absorption of high-energy X-rays and ultraviolet (UV) radiation from the Sun. However, because the gas molecules are so dispersed, there isn’t enough density for this heat to be felt in the same way it would be at lower...
Of course, these molecules may have a different mechanism of action for their antibacterial potential, but we are here underlying the structural features, which have been known to impart antibacterial potential to oxazolidinones so, that we can understand what else can be done with this core to ...
Which of the molecules are polar? {eq}a. H_2O\\ b. CH_4\\ c. HF\\ d. NH_3\\ e. CH_3F\\ f. BeCl_2 {/eq} The polarity of molecules: To be a polar molecule, the first criterion is bond must be polar. Now the EN of Carbon is 2.55 and ...
