IUPAC General
How do you number the parent chain? What happens when two different paths of numbering give you the same length parent chain?
So that the substituents have the lowest carbon locator. If two paths are the same length, choose to number so there are a greater number of substituents.
what is the common name of a 3- carbon chain attached to an amine?
Propylamine
In a cylcocarbon which substituent gets the lower number; 2-carbon chain or 3-carbon chain? Why?
2-carbon chain, because e comes before p.
What is the name of a 4-carbon chain ending with a fluorine?
1-fluorobutane
When a cylclocarbon has only one substituent how is it numbered?
It isn't numbered.
Are tert-, or sec- considered when alphabetizing substituents? If not, which prefixes are? If yes, give an example of an 8-chained parent group with at least 3 substituents, including 1 sec- or tert-.
No, prefixes that do matter for alphabetization, when connected to substituents are di-, tri-, tetra-, penta-, etc.
What is the name of an unsymmetrical ether attached to a 6-carbon chain and 8-carbon chain?
hexyl octyl ether
What is the correct name, 1,2-dimethyl-5-propylhexane, or 5,6-dimethyl-2-propylhexane?
1,2-dimethyl-5-propylhexane
What is the name of a secondary amine, with a 2-carbon chain attached to it, (and the amine is) branching off the second carbon of a 5-carbon chain.
N-ethyl-2-pentamine
How do you decide which substituent to give a lower carbon locator on a cylclocarbon?
The substituent which comes first alphabetically is given the lower number if there are only 2. If more than 2 substituents are attached, they are numbered so more substitutions have lower numbers.
Why can the prefix sec- only be attached to a butyl group?
Because names must specify only one compound and any chain shorter than 4 sec- would be the parent chain and for any chain longer, sec- could refer to more than one compound.
What is the common name of a 5-carbon chain attached to an alcohol?
pentyl alcohol
What is correct:
3-isopropylhexane
or
3-ethyl-2-methylhexane?
3-ethyl-2-methylhexane
What is the name of a 7 carbon chain with two alcohols on either end and a methyl group on the 3rd carbon?
3-methyl-1,7-hepanediol
What would the name of the following molecule be?
5,5-ethyl-3-methyl-2-propyl-1-cylclohexanol
For parenthetical names, what is included in the parentheses?
The carbon locator of the branch is included outside of the parentheses, in the parentheses the branch of the substituent is proceeded by its caron locator, followed by the name of the branch followed by the name of the "parent" substituent, then the closing parentheses is followed by either additional substituents or the parent chain.
What is the common name of a 8-carbon chain attached to a bromine?
octyl bromide
When 2 substituents would are equal distance from the ends of a carbon chain, which gets priority? the alphabetically first, of the larger one?
the one that is alphabetically first
What is the name of a symmetrical ether attached to two 5 carbon chains?
pentoxypentane
What is the name of a cyclohexene with alternating double bonds?
phenyl
What is the general format of an IUPAC name with a functional group included? Please give an example with a 10-carbon chain with two methyl groups on the 3rd carbon and an alcohol branching off the 4th carbon
[substituents][parenthydrocarbons][functional group suffix]
ex: 3,3-dimethyl-4-decanol
Is isobutane a common name?
Yes.
What is the name of a 5-carbon chain ending with an aldehyde?
pentanal
What is the name of a quaternary ammonium salt with a 3-carbon, 4-carbon, 2-carbon, and 9-carbon chain attached to it? (with a chlorine anion)
N-(butyl)(ethyl)(nonyl)(propyl)ammonium
and Chloride
What would the name of the following molecule be:
molecule 2
1-fluro-3-isopropyl-5-methyl-phenyl
