Orgo Reactions What you need to know about organic chemistry.

What to know Functional group identification –General characteristics (acid/base, happy/bad smell, solubility in water.) Naming branched hydrocarbons –Simple functional group (alcohol, halogens) –Identifying chirality Reactivity –Oxidation/reduction of C-O bonds –Substitution at a carbonyl (polymers) –Addition reactions (polymers) –Halogen reactivity

alcohol Ketone Aldehyde Carboxylic acid NaBH 4 or LiAlH 4 decrease the number of C-O bonds. KMnO 4 or Cr +6 increase the number of C-O bonds.

This molecule can be any of the following functional groups: Ester, amide, carboxylic acid, acid halide. This molecule can be any of the following functional groups: Alcohol, water, amine, carboxylic acid, metal hydroxide IF a molecule has two functional groups, this can potentially build a polymer! Substitution at a Carbonyl

Addition Reactions Addition polymers: Adding H 2 requires a catalyst (Rh, Pd)

Other substitution rxns This reaction is informational only. Other classes will talk about this.

Combustion of Organic Molecules C x H y + excess O 2 CO 2 + H 2 O C x H y O z + excess O 2 CO 2 + H 2 O C x H y N a O z + excess O 2 CO 2 + H 2 O + NO 2 Of course this assumes complete combustion.
