Ch. 20 Carbon & Hydrocarbons Carbon is mainly found combined with other elements What are some examples of carbon with other elements? Petroleum, natural gas, sugars, wood, ANY THING LIVING HAS CARBON What are some examples of carbon by itself? Coal, diamond, graphite
WWhy does carbon combine so well with elements? ++4, -4 charge CCarbon atoms form rings & chains CCarbon can form a loose bond arrangement or a tight symmetric bond. DDiamond tight GGraphite loose
Graphite Very loose arrangement Good lubricant Graphite pencils Graphite composites metals & graphite combined together Golf club, racquet, bats
Diamonds Tight arrangement Mined in Africa (mainly) Densest form of carbon Hardest mineral Used in drilling, grinding, & cutting
Amorphous Carbons – decomposed carbons by heat 11. Coal – from decomposed organic compounds 22. Peat – partially carbonized plant material. Used as fertilizer 33. Coke – residue left from heating bituminous coal. 44. Charcoal – residue from heating wood.
Organic Chemistry Any compound with carbon in it. Carbon can form a single, double, or triple bond. Hydrocarbons are compounds with carbon & hydrogen. Substitute hydrocarbons are compounds with H, C, & a third element.
