|
Definition
Alkene gives alkane
Alkyne gives alkene |

|
Definition
| One Br on each of the two carbons involved in the double bond |

Term
| Common solvents for proton NMR |
|
Definition
Really anything with D instead of H (CDCl3, CD3CN, D2O) and CCl4
If it has an H it's not a common solvent |

| Location of a signal on a proton NMR says... |
|
Definition
| The electronic environment of absorbing protons |
|
|
Term
| If the MHz of the spectrometer used changes, does the location of the signal? |
|
Definition
NO
i.e. if a signal is at 3.5ppm with a 60-MHz spec, it's at 3.5ppm with a 300-MHz spec |

| How to determine oxidation levels |
|
Definition
1. find molecular formula
2. C=X, H=1, O=-2
3. set equation = 0 and solve for X
4. greatest X > lowest X for oxidation level |
