|
|
Term

|
|
Term
What forms do amines take on and what are the various properties that they undergo? |
|
Definition
Amines form RxN(Hx)(x) compounds. They form primary, secondary, tertiary and quaternary forms. In the tertiary neither the hydrogen nor positive charge is present and in the quaternary form it is called an ammonium ion instead of an amine as in all other forms |
|
|
Term
How do phosphines differ from nitrates in regards to their organic compound bonding properties? |
|
Definition
The only thing that is changed is that instead of dealing with nitrogen as the base atom you're dealing with phosphorous. The primary, secondary, tertiary and quatrnary paterns are the same and the quaternary form is called a phosphonium ion |
|
|
Term
How are aldehydes and ketones similar in functional groups? |
|
Definition
Aldehydes have the RCHO formula (NOT RCOH) so one end has a terminal hydrogen and an oxygen is double bonded to a carbon whereas for ketones both ends are non-terminal with the oxygen double bonded |
|
|
Term
How do nitro compounds bond to various organic groups? |
|
Definition
You'll always find the NO2 group attached but it may or may not be double bonded to one of the oxygens. If it is double bonded then the charge of the nitrogen becomes positive and the oxygen becomes negative resulting in a resonance structure |
|
|
Term
How are nitriles set up in relative molecular settings? |
|
Definition
They always have a C---N group (carbon triple bonded to nitrogen) and either a terminal hydrogen to form cyanide or a more complex organic compound group |
|
|
Term
Describe how anides are set up |
|
Definition
Anides always contain the N3 anide group. One nitrogen is always positively charged and another is always negatively charged. In the case that nothing else is bonded to it both ends are negative |
|
|
Term
What happens if you replace an -OH group in sulfuric acid with an organic group? |
|
Definition
You will produce a sulfonic acid which can go on to form many different molecules because of its open organic end |
|
|
Term
Pretend you need to create a new compound which has a certain set of characteristics. What property could you use to facilitate this endevor? |
|
Definition
Use the combination of functions. With this property you can combine the properties from multiple compounds and combine them into a novel compound |

How does the amount of constitutional isomers change as more carbons are added to a carbon chain? |
|
Definition
The amount increases exponentially. Even at C10H22 you're looking at 75 isomers |
|
|
Term
What is the be-all-end-all rule regarding nomenclature? |
|
Definition
Any name stands for only one compound |
|
|
Term
What is the first step to naming organic compounds? |
|
Definition
Determine the longest straight chain. If there is a tie, pick the one with the most constituents |
|
|
Term
What is the second rule in naming organic compounds? |
|
Definition
Determine the name of all alkyl groups, note their positive and put them in alphabetical order |
|
|
Term
What is the third rule in naming organic compounds? |
|
Definition
Number the chain so that the lowest number goes to one of the alkyl groups. In the case of some sort of tie the winner is the chain in which the lowest number comes next |
|
|
Term
What is the fourth rule in naming organic compounds? |
|
Definition
In the case of multiple occurances of the same alkyl group (ex. methyl) use the appropriate standard prefix (if 3, use ...-trimethyl...) |
|
|
Term
What are the rules on alphabetizing organic compounds? |
|
Definition
Certain prefixes such as "iso-" are counted but others such as "cyclo" and the common numeral prefixes don't count |
|
|
Term
What is the prefix for single atoms attached to organic chains? |
|
Definition
It depends on the atom. For example, flouride is "fluoro-", Chloride is "chloro-", Bromine is "bromo-", Iodine is "iodo-", etc. |
|

Term
Can NO2 be used as either a prefix or a suffix? Also, what is its abbreviation? |
|
Definition
NO2 is always used as a prefix no matter what. Its prefix is "nitro-" |
|
|
Term
Is there either a prefix or suffix to denote the -OR chain in an organic compound? Also, what group of letters is used in the name? |
|
Definition
It is always a prefix. The prefix used is "-oxy". In the case that it is by itself the prefix is "alhoxy", with a methyl group the prefix is "methoxy" and so on |
