|---|---|---|---|---|---|
| show | prior to wohler's experiment, the prevailing view was that only living organisms could synthesize "organic" compounds. Wohler made urea, an organic compound without the involvement of living organisms.
🗑
|

| show | the spark provided energy needed for the inorganic molecules in the atmosphere to react with each other*
🗑

| Draw a structural formula for C2H4 | show 🗑
|
||||
| show | isomers are compounds that have the same number of atoms of the same elements but different structures with different properties. Structural= differ covalent arrangement, cis trans have covalent bonds the same but different spacial arrangement.
🗑
|
||||
| show | enantiomers are isomers that mirror images of each other differing in shape from asymmetric carbon one attached to four different atoms
🗑
|
||||
| what does the term amino acid signify about the structure of such a molecule? | show 🗑
|
||||
| show | both consist largely of hydrocarbon chains
🗑
|
||||
| show | no because there is not enough diversity in the atoms. It can't form structural isomers because there is only one way for three carbons to attach to each other. There is no double bonds so cis trans isomers is not possible. Each carbon molecule has two
🗑
|
||||
| show | hydrogen attatched so the molecule is symmetrical and cannot have enantiomers
🗑
|
||||
| what chemical change occurs to ATP when it reacts with water and releases energy? | show 🗑
|
||||
| show | a group that can act as a base is replaced by a group that can act as an acid, increasing the acidic properties of the molecules with which it can interact. The original cysteine molecule has an asymmetric carbon in the center. After replacement of the

| How did Stanley Miller's experiment extend the idea of mechanism to the origin of life | show 🗑
|
||||
| show | Acetone and propanal are structural isomers. Acetic acid and glycine have no asymmetric carbons, whereas glycerol phosphate has one. Therefore glyerol phosphate can exist as forms that are enantiomers, but acetic acid and glycine cannot.
🗑

||||
| In what ways does a methyl group differ chemically rom the other six important chemical groups? | show 🗑
|
||||
| show | the study of carbon compounds
🗑
|
||||
| which chemical group is most likely to be responsible for an organic molecule behaving as a base? | show 🗑
|
||||
| which of the following hydrocarbons has a double bond in its carbon skeleton? | show 🗑
|
||||
| show | structural isomers
🗑
|
||||
| how do you identify an asymmetric carbon* | show 🗑
|
||||
| show | the replacement of the -oh of a carboxy group with a hydrogen
🗑
|
||||
| show | since it has 4 valence electrons, just like carbon, silicon would be able to form long chains, including branches, that could act as skeletons for large molecules. It would do better than neon with no valence or aluminum with only three.
