How do you tell the difference between Organic
How do you tell the difference between Organic* and Inorganic Compounds? Assembled By T. Brown 2012 * For purposes of this discussion we are using the term “organic” as the formal chemistry meaning used to divide chemistry into two fields of living and nonliving. We are not (for purposes of this discussion) using the “grocery store” definition of “organic foods” grown naturally without synthetic pesticides, herbicides, growth hormones, etc. . . By T.

How do you tell the difference between Organic and Inorganic Compounds? INORGANIC GENERAL RULES: • Sometimes Contain Carbon • Many do not include CARBON. • Not associated with Living Organisms. ü ü EXAMPLES Oxygen O 2 Table salt or Sodium Chloride, Na. Cl Carbon Dioxide, CO 2 *Even though it contains Carbon. Diamond (pure carbon) ORGANIC GENERAL RULES: • ALWAYS Contain Carbon • MOST contain Carbon – Hydrogen Bonds • Most always associated with living organisms. EXAMPLES: ü Glucose C 6 H 12 O 6 ü Carbon Tetrachloride CCl 4 *Notice this is classified as organic, without C-H bonds. ü Urea CO(NH 2)2 EXCEPTIONS TO THE RULE & CONFUSING BITS: EXEPTIONS TO THE RULE & CONFUSING BITS: So if it contains carbon, it may be classified as organic, “For historical reasons, a few types of carboncontaining compounds such as carbides, carbonates, simple oxides of carbon (such as CO and CO 2), and cyanides, as well as the allotropes of carbon such as diamond and graphite, are considered inorganic. The distinction between "organic" and "inorganic" carbon compounds, while "useful in organizing the vast subject of chemistry. . . is somewhat arbitrary”. 1 but a few of things like CO 2 that are essential to life processes and contain carbon are not classified as organic because “that’s the way we’ve always done it. ” (sigh) We do however include deadly poisons and other synthetic chemicals which are never found in nature. (This is ironic considering the other “grocery store” definition of organic. ) References Drawn Upon… http: //chemistry. about. com/od/branchesofchemistry/f/What-Is-The-Difference-Between-Organic-And-Inorganic. htm 1 Spencer L.
