Question: Decide whether the following compounds/ions are polar or nonpolar. a. {eq}\rm IF_3 {/eq}. b. {eq}\rm BrCl_3 {/eq}. c. {eq}\rm NF_3 {/eq}. Polarity: Charge distribution and geometry or structure of compound, both play important role to determ...
Is ethyl acetate a polar or non-polar solvent? What do nonpolar tails do? Why is proline nonpolar? Why does AgCl dissolve in NH3? Compare and contrast the intermolecular forces in alcohols and ethers. What type of intermolecular force is present in alcohols that are not present in ethers?

Is benzene polar or nonpolar? In case of benzene, it isa non polar moleculebecause it contains only C-H and C-C bonds. Since carbon is slightly more electronegative than H , a C-H bond is very slightly polar and has a very small dipole moment. Which of the following is most soluble ...

a7) Wash the non-polar solvent with warm distilled water wash, cool distilled water wash, and a third warm water wash. Continue washing until the washes are clean. After the third wash, monitor the pH and do not allow it to fall below pH 9. If necessary to remove excess sodium ions,...
Lubricant is to be able to improve plastic processing flow properties of a kind of additive, its structure generally has a long chain of nonpolar and polar group two parts, in addition to improve the melt flow, it also has promotes molten, easy stripping, prevent electrostatic, prevent adhesion...
a Fluid mosaic model describes a membrane as a continuous bilayer formed by lipids with the polar heads oriented toward the outside and the nonpolar heads towards the center of the membrane. Embedded at numerous sites in this bilayer are various sized globular proteins. 流体镶嵌模型描述一个膜作为...
What are polar and nonpolar bonds?Chemical Bonds:A chemical bond is a type of intramolecular force that is between the atoms in a compound. A lewis dot structure can represent the presence of bonds and electrons in a compound. The chemical bond can be further classified as ionic or covalent...
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....
