Document Summary
Organic compound structures: at the end or intersection of each line, there is one carbon with enough hydrogen to give 4 bonds total. Aldehydes (r-c=o-h: heptanal smells like sage, octanal smells like oranges, nonanal smells like roses, tridecanal smells like grapefruit. Ketones (r-c=o-r": voc volatile organic compounds. Carboxylic acids (r-c=o-oh: ethanoic acid/acetic acid vinegar, butanoic acid/butyric acid butter, tetradecanoic acid (14 carbons) nutmeg. Esters (r-c=o-o-r": ethylbutyrate pineapple, ethylcinnamate cinnamon, benzocaine alleviate pain. Amines (r-nh2 or r-nh-r": primary, secondary and tertiary amines depends on how many carbons are attached to the nitrogen. Amides (r-c=o-nh2: piperine black pepper, caffeine. Ar (arsenic), cr (chromium), cd (cadmium), sb (antimony), hg (mercury), tl (thallium) Radio < microwave < infrared < uv < x-ray < gamma. Long wavelength (inverse relationships between energy and wavelength) (direct relationships between energy and frequency) Color transmitted is the complement to the color absorbed (ex. red and green, orange and blue, yellow and violet)
