Assignment Four Colligative properties refer to properties of the solvent that are affected by the presence/absence of solute particles. As such, they are dependent on the physical reaction of the solute and the solvent—there are no chemical reactions involved. All responses to the following questions should use language and terms that a high school senior that hasn't taken AP chemistry. 1) Why does the addition of solute decrease the melting point, and increase the boiling point of the solvent? 2)...

A compound with the molecular formula of C7H16 has the following physical properties: mp= -123.8 C; bp= 79.2 C; density = 0.6739 g/mL. There are several compounds with that formula. Use a reference book to determine the name and the structural formula of the isomer with those specific properties. Hint: Use the boiling point index at the end of the section “Physical Constants of Organic Compounds” in the CRC Handbook of Chemistry and Physics. Determine the boiling point, water solubility...

Many of the water properties lead to some crucial physical, chemical and biochemical processes that are closely related to environmental and health problems. Some people state: (I) A relatively high dissolution of O2 in water is due largely to the dipolar property of water molecules. (II) Although the density of water changes only slightly with temperature, its change can cause lake water turnover or stratification. (III) Since water dissociation is so small (H2O ó H+ + OH-, Ka = 1.0...

Lab : Aldol Condensation Purpose. In this lab you will conduct the Aldol condensation reaction under solid-state reaction conditions that will involve grinding reactants in the solid phase. You must read ahead and learn about this reaction and the chemical mechanism for the Aldol condensation. There are two possible products which are the initial Aldol or subsequent elimination product. You will need to isolate and purify your reaction product. You will use your melting point, IR, 1H and 13C NMR spectra to...
