Examples
(click on images to make them larger) |
1 | All that contains C, H, O | Combustion |
Oxygen (O2) is always a reactant Limited by heat |
CO2 + H2O |
Must Balance these equations, using molecular formula in equations. |
|
2 | Hydrocarbons RCH2CH3 |
|||||
3 | Alcohols, RCH2OH |
|||||
4 | Aldehydes, ketones R1C(O)R2 |
Aldehydes / ketones are constitutional isomers | ||||
5 |
Esters, carboxylic acids R1CO2R2 |
Carboxylic acids / esters are constitutional isomers | ||||
6 |
Alkenes, (R-CH=CH-R) |
Addition | H2O in acid (H+) | 1o, 2o, or 3o alcohol |
Hydration reactions follow Markonikoff’s Rule – rich get richer Reverse of dehydration of alcohol reaction (Rxn #10) |
|
7 | H2 | alkane | Hydration rxn | |||
8 | HCl, HBr, HI | Alkyl halide | Hydrohalogenation reaction follows Markonikoff’s Rule | |||
9 | Cl2, Br2, I2 | Alkyl di-halide | Halogenation reaction | |||
10 | Alcohol – hydroxyl |
Elimination |
Acid Catalyzed (H+) with heat There must be a H on an adjacent C otherwise there will be no rxn |
Most substituted alkene |
Sayseff’s Rule – Poor get poorer |
|
11 | Alkyl Halide | Base Catatalyzed (OH-) An alsohol also acts as part of the catalyst |
||||
12 | Alkane | Substitution | A Pt (s) catalyst and UV light are required | Alkyl halide | The relative amounts of the various products depend on the proportion of the two reactants used. | |
13 | Alcohol | Alcohol reacts with a hydrogen halide | ||||
14 | Alkyl halide | Alkyl halide reacts with a hydroxide ion | Alcohol | |||
15 | Alkyl halide | Allkyl halide reacts with ammonia, 1o or 2o amine | 1o, 2o or 3o amine | |||
16 | 1o alcohols RCH2OH |
Oxidation |
[O] conditions Some OA: CrO3, H2CRO4, K2Cr2O7 |
1o gives aldehydes first, then carboxylic acids | Reverse of reduction of aldehydes (Rx#15) | |
17 | 2o alcohols, R1-CH(OH) – R2 |
2o alcohols gives ketones | ||||
18 | 3o alcohols, R1-C(R2)(OH) – R2 |
3o alcohols do not undergo oxidation | ||||
19 | Aldehydes, R1 - CHO |
[O] conditions Some OA: CrO3, H2CRO4, K2Cr2O7 Tollens (Ag+) NAD+ (biological) |
Aldehydes give carboxylic acids | |||
20 | Ketones, R1 - C(O) - R2 |
Ketones do not undergo oxidation | ||||
21 | Alkyne Alkene |
Reduction | [H] Reducing agent |
Reduction of Alkyne give Alkene Reduction of Alkene give Alkane |
||
22 | Aldehyes | Reduction of aldehyes produces a 1o alcohol |
||||
23 | Ketone | Reduction of Ketones produces a 2o alcohol |
||||
24 | Carboxylic Acids | Reduction of carboxylic acid produces first an aldehyes and then a 1o alcohol | ||||
25 | Alcohol | [H] Common catalyst: Al2O3 |
Alcohols will produce alkene | |||
26 | Carboxylic Acids, |
Neutralization | Reaction with any base, Usually OH- or any amine |
Carboxylate ion Carboxylate ion + ammonium ion |
||
27 | Condensation - Esterification |
Reaction of any carboxylic acid with any alcohol, catalyzed by heat and acid | ester | Catalyzed be acid. Anhydride + alcohol gives ester product without acid catalysis |
||
28 | Condensation - Amide production |
Acid + amine + heat | Rxn with 1o or 2o gives an amide Rxn with 3o does not give an amide, only neutralization product |
Same as amine formation desciribed below | ||
