| Classification of Reactions | 1a | Combustion of Methane Balloons | Ignition of balloons containing methane and methane + oxygen |
| Density differences | |||
| Stoichiometry | |||
| Balanced equation | |||
| 4a | Light Initiated Bromination of Pentane | Bromine is added to 2 test tubes containing pentane. One tube is masked, and the other irradiated with light. The tube exposed to light looses the bromine color and pH paper shows evolution of an acidic gas. | |
| Structure of 3 monobrominated isomeric products are shown | |||
| Mechanism of free radical substitution is shown | |||
| 4b | Bromination of Hexane Isomers | Relative rates of reaction of 2 hexane isomers with bromine in light | |
| Mechanism of free radical bromination | |||
| 6b | Addition of Oxygen to Tetrakis(N,N- dimethylamino)- ethylene | A test tube of the alkene is shaken with oxygen in the dark. A greenish glow is observed. | |
| Chemiluminescence | |||
| Equation | |||
| 7a | Preparation and Combustion of Acetylene | Calcium carbide lumps are dropped into a beaker of water. Bubbles of acetylene are produced. Acetylene is ignited to produce a sooty flame. | |
| Equation | |||
| 11c | Lucas Test for Primary, Secondary, and Tertiary Alcohols | Isomers of butanol are treated with an aqueous mixture of ZnCl2 and HCl. The tertiary alcohol reacts immediately to form a cloudy solution. The secondary alcohol reacts more slowly. | |
| Catalysis | |||
| Equation | |||
| 12d | Silver Mirror - Tollens' Test for Aldehydes | redox reaction | |
| preparation of silver mirror | |||
| equation | |||
| 16a | Formaldehyde Copolymers | Polymers of formaldehyde with phenol, urea and aniline are prepared and properties compared. | |
| Commercial products of Bakelite and urea-formaldehyde resins. | |||
| 16b | Synthesis of Nylon(6,6) - Nylon Rope | Nylon forms at the interface of 2 immiscible liquids and is pulled from the solution as a rope | |
| Equation | |||
| 18a | Dehydration of Sucrose with Sulfuric Acid | sucrose (table sugar) and conc. sulfuric acid react in a highly exothermic manner to form a cylinder of carbon that "grows" out of the beaker | |
| exothermic reaction | |||
| biochemistry | |||
| 18d | Oxidation of Sucrose with Potassium Chlorate | Sucrose bursts into flame when oxidized by potassium chlorate | |
| exothermic reaction |
