organic chem exam 2
| Question | Answer |
|---|---|
| hydrocarbons | primarily derived from crude oil |
| glycoprotein | transport cholesterol for example made up of carbs and proteins, main job to help with transport of cholesterol |
| cholesterol | an alcohol that requires glycoproteins to be transported around the body because they are largely nonpolar structures that dont react well with water |
| ethers are primarily used for | surgical procedures |
| what are the 4 that are lowk the same base and then the one branch changes | aldehyde, ketone, ester, and carboxylic acid R—carbonyl group—CHANGES |
| aldehyde | R—carbonyl group—H |
| ketone | R—carbonyl group —R |
| carboxylic acid | R—carbonyl group—OH |
| ester | R—carbonyl group—O-R |
| amide | R—carbonyl group—N-2 Rs, could be H2 |
| ether | R—O—R |
| alcohol | —OH can have primary secondary or tertiary types, depending on how many carbon based groups are connected to the central atom hanging onto the OH |
| aromatic compound | the ring with 3 double bonds aka the circle in the middle |
| phenol | the ring connected to an OH not an alcohol + aromatic but visually it looks that way |
| amines | NH3 except to some degree H are replaced by carbon based compound primary (methyl amine), secondary (dimethyl amine) and tertiary (trimethyl amine) |
| methane | molecular formula: CH4 condensed structural formula:: CH4 |
| Ethane | C2H6 condensed structural formula: CH3H3 |
| propane | C3H8 CH3-CH2-CH3 |
| butane | C4H10 CH3-CH2-CH2-CH3 |
| pentane | C5H12 CH3CH2CH2CH2CH3 |
| hexane | C6H14 CH3CH2CH2CH2CH2CH3 |
| heptane | C7H16 CH3CH2CH2CH2CH2CH2CH3 |
| octane | C8H18 CH3CH2CH2CH2CH2CH2CH2CH3 |
| nonane | C9H20 CH3CH2CH2CH2CH2CH2CH2CH2CH3 |
| decane | C10H22 CH3CH2CH2CH2CH2CH2CH2CH2CH2CH3 |
| undecane | C11H24 CH3CH2CH2CH2CH2CH2CH2CHCH2CH2CH3 |
| which is the most dominant cyclohexane shape | chair lowest energy |
| what is the second most dominant cyclohexane shape | boat second lowest energy |
| angle strain | when the bond angles are less than optimal, aka not 109.5 present in the flat form of cyclohexane, when it is in the chair or boat formations this is resolved |
| torsional strain | when the substituents/groups on 2 ADJACENT C that are too close together,,,interact |
| 1,3-diaxial strain | when two groups are kinda having a torsional strain issue aka too close, but the C they’re on are not adjacent like 3 C away from each other a specific type of steric repulsion |
| steric repulsion | |
| stereoisomer | have the same name and molecular connectivity but different orientations in space relative to plane different spacing between atoms |
| diasteromers | stereoisomers that cannot be related by a mirror plane cis vs trans for example if its not an enasteromer, its a diasteromer |
