How to Retain Polar and Nonpolar Compounds on the Same HPLC ...

How to Retain Polar and Nonpolar Compounds on the Same HPLC Stationary Phase with an Isocratic Mobile Phase High performance liquid chromatography (HPLC) stationary phases can be segregated by their ability to separate either polar on nonpolar compounds, that is, reversed-phase materials (C18 ...

Bond and Molecule Polarity Worksheet

Think about it: The proteins in many cells contain both polar and nonpolar side chains. The nonpolar side chains are usually found on the inside of the protein, while the polar side chains are found on the outside facing the cell's cytoplasm, which is mostly water.

Which molecule is nonpolar and has a symmetrical shape?

Name: _____ 1) Which molecule is nonpolar and has a symmetrical shape? A) NH 3 B) H 2 O C) HCl D) CH 4 2) When ammonium chloride crystals are dissolved in water, the temperature of the water decreases.


The bottom edge of the paper is then placed into a nonaqueous (i.e. nonpolar) mixture of acetone and petroleum ether. As the solvents migrate up the paper by capillary action, those pigments in the mixture that are nonpolar will dissolve in the solvents and travel upwards.

Lab #3: Solubility

This rule is most commonly applied to polar and nonpolar compounds. According to this rule, a polar solvent will dissolve polar (or ionic) compounds and a nonpolar solvent will dissolve nonpolar compounds.

Teacher's Preparatory Guide Lesson #1 - Polarity and ...

In molecules with nonpolar bonds, there is an equal sharing of electrons (C-C bond). A molecule can be made up of polar bonds yet it is nonpolar if these bonds are equally dispersed throughout the molecule and there is no net dipole moment.


This type of bond is called a nonpolar covalent bond. A nonpolar covalent bond is one in which the sharing of bonding electrons is equal. When two atoms involved in a cova1ent bond are not identical (atoms of different

Cl–Cl ∆EN = 0, ∴ the bond is nonpolar covalent . H–F ∆EN = 1.9, ∴ the bond is polar covalent . H–C ∆EN = 0.4, ∴ the bond is nonpolar covalent
