1.Polar molecules have one end that is more negative(it has the electrons more of the time) and one end that is positive(it has the electrons less of the time) In other words the electrons that are shared in the covalent bond are not shared evenly. Therefore, it can attract other things that are polar. Non polar molecules share evenly and do not have a partial charge so do not attract things that have charges.
given the following electronegativities Na=0.9, H=2.1, Cl=3.0 which of the following statements is true? H2,Cl2, and HCl are polar covalent molecules NaCl is a polar covalent compound and HCl is an ionic compound HCl is a nonpolar
A compound that you are studying is soluble in CCl4 but not in water. Would you predict that the compound is polar or nonpolar? Why? [Please explain; don’t just give a trivial answer such as “Because like dissolves like”.]

A few questions. 1. What is the difference btwn crystalization and precipitation? 2. What will happen if you choose a solvent whose boiling point is higher than the melting point of the compound to be crystalized? 3. Generally
Using electronegativity arguments, classify the following diatomic molecules as nonpolar (N), polar (P), or ionic (I), and enter five letters in order (e.g. NPNPI, INPNP, etc) : NaF, HF, NaH, CaO, and F2. Look up electronegativity
