Aldol Reactions: Benzalacetophenone and Dibenzalacetone

Procedure: "In a 125-mL Erlenmeyer flask containing a magnetic stirring bar, mix 0.05 mol of benzaldehyde with the theoretical quantity of acetone, and add one-half the mixture to a solution of 5 g of sodium hydroxide dissolved in 50 mL of water and 40 mL of ethanol at room temperature (<25oC). After 15 min of stirring, add th

Medications and Organic Compounds

I am to identify organic compounds in medications. I chose to look at Orajel first. I am to determine the structure of one active component and identify three functional groups on each molecule. Based on the functional groups present in the drug molecules, predict the physical properties of the molecule the drug would interact

Functional Groups of Carbon

Carbon is a fascinating element that is capable of forming four covalent bonds. Remembering molecular geometry, an element bonded to four separate atoms forms a symmetrical tetrahedron. When the elements are either carbon or hydrogen the molecule is nonpolar. Nonpolar compounds are insoluble in water. Examples of this includ

Decomposition Rate

A monoprotic organic acid decomposes after an enzyme is added to the solution. The initial concentration of the acid is 1.55 mol/L. After 354 sec, you take a 15.00 mL sample, titrate it with 0.120 mol/L NaOH solution, and reach the equivalence point after adding 52.36 mL. Compute the average decomposition rate of the organic

Wavelength of light required to break C-C, C-Cl & O=O bonds

Without stratospheric ozone (O3), harmful solar radiation would cause gene alterations. Ozone forms when O2 breaks and each O atom reacts with another O2 molecule. It is destroyed by reaction with Cl atoms formed when the C-Cl bond in synthetic chemicals breaks. Find the wavelengths of light that can break the C-Cl bond AND the
