Biology Notes: Grade 12

Organic Chemistry Classification study of simple/ synthetic substance/complex C- fluxs petroleum products and by-products: positive puppet/vegetable, inorganic mineral (produced chemicals but now they are synthesized without having to extract, in any circumstance carbonate & antiophthalmic factor; cyanide compounds) 6 common organic compounds in order of abundance from least to close to: S, P, N, O, C, H Bergelius Vital supposition: forces produce compounds in living things besides Vohler, German scientist: 1824, produced oxalic demigod COOH COOH & 1828 produced urea other scientists began to synthetically produce acetic acid, benzene lab Covalent coheres Catenation: C atoms coupled together in chain or anchor ring/cyclo London forces b/w organic molecules Isomers: one molecular(a) reflection could play more than one organic compound Chemical properties determined by the available groups ____________________________________________ Hydrocarbons Non-polar, hydrophob ic most C stick bys covalently with H Branched, unbranched, rings, shapes, 1x/2x/3x bonds Aliphatic: open chain, alkane C-C, olefin C=C, alkyne, cyclo, frosting/eth/prop/but/pent/ enchant/hept/non/dec Aromatic: benzene ring, mother aroma (scent) ie. benzene C6H6, see Kekule Hydrocarbons below C-H bonds consistent space with C-H bonds of hydrocarbons (C-C > C-_-_-C bond length All C-C have resembling length/reactivity = geomorphological formula written as I/II/ third plangency Formula ____________________________________________ Polar soluble in water, hydrophilic (alkanes/parafines) CO: diatomic (2 atoms of same/different elements) single H (HCl), OH (C2H5OH), O (OCl), N (NF3) alcohol (hydroxyl), aldehyde/ketone (carbonyl), carboxylic acid (carboxyl), amine (amino) Non-Polar non-water-soluble in water, hydrophobic (alkenes/ynes) all elements Cl2 most C compounds: oil, CO2, CH4 ____________________________________________ everlasting(a) Hydrocarbons single C-C bonds, a lkanes/parafines Max # of H atoms Fats Subst! itution reaction unsaturated Hydrocarbons Double C=C or triples bonds, alkenes, alkynes, non-polar Oils, Teflon, Plexiglass (contacts), synthetic substance rubber (Cl radical), innate Rubber (methyl radical), tire rubber, (black since C-S not C-H monomers, olfactory perception since Sulphur burns) Addition reaction Polyunsaturated 1+ 2x bond Polymers Chain molecules of like monomer units (held by Van der Waals Forces) Polysaccharides, plastics Monomers... These notes are very thorough and parcel out many topics in Biology, the besides thing I would bespeak is a little dampen organization but general very good!
