through different tests. The samples were n-butyl alcohol, sec-butyl alcohol, tert-butyl alcohol, acetaldehyde, n-butyraldehyde, benzaldehyde, acetone, acetophenone, and isopropyl alcohol. Each of the samples were tested through solubility test of alcohols in water, Lucas test, Chromic acid test or the Jones oxidation test, 2,4-Dinitrophenylhydrazone (2,4-DNP) test, Fehling’s test, Tollens’ silver mirror test, and Iodoform test. Solubility test of alcohols in water was used to determine the amount of

CHAPTER 15 ORGANIC COMPOUNDS AND THE ATOMIC PROPERTIES OF CARBON 15.15 a) Octane denotes an eight carbon alkane chain. A methyl group (–CH3) is located at the second and third carbon position from the left. CH3 CH3 CH CH CH2 CH2 CH2 CH2 CH3 CH3 b) Cyclohexane denotes a six-carbon ring containing only single bonds. Numbering of the carbons on the ring could start at any point, but typically, numbering starts at the top carbon atom of the ring for convenience. The

stretches. To the right of the aromatic C-H stretches, it was appeared a shoulder-type peak at 2872.07 and 2732.33 cm-1, which proves the presence of aldehyde group. In the IR graph, a very weak peak at 3396.06 cm-1 can be found. It falls in the alcohol group range, but it is very weak. Considering the actual lab situation, it is more likely to be the water group. The NMR graph doesn’t support this specific lab result since it is from another sample. This specific NMR result indicates a successful

attack. Because the carbonyl contains no good leaving group, addition occurs rather than substitution. Aldehydes and ketones are polar compounds; however, the pure compounds do not undergo hydrogen bonding as the alcohols do. Thus the boiling points of aledehydes and ketones are lower than alcohols, but higher than alkanes or ethers. Low molecular weight carbonyl compounds are water soluble. Tests used to classify aldehydes and ketones Question 1 Identify the tests used to classify aldehydes and ketones

Alcoholism in teens In my opinion there is no upside to teens using alcohol. The fact of the matter is that the number of teens using alcohol is a grim signal of what is going on in the American family. One of the major causes of teen alcohol is home life.

This is by far one of the most disheartening
