ether nomenclature

- Chain is separated by a single bonded "O" -add "oxy" to the smaller group -Larger group gets the parent name

How do you name an Alkene/Alkyne

-Identify longest parent chain -double bond is "ene" -Triple bond is "yne" -number the chain starting at the end closest to the multiple bond

Ketone nomenclature

-Longest chain ending is "one" -location of double bonded "O" must be numbered and gets owest number priority -Other attachments are named before

Alcohol Nomenclature

-Longest chain with the hydroxyl group, ending will be "ol" -attachments are named infront of the main chain

haloalkane nomenclature (F, Br, Cl, I)

-Longest parent chain -give lowest numbers priority

Amides nomenclature

-contains a double bonded "O" and an N -The molecule splits at the "O" -the parent chain ending is "amide" -the N part of the molecule is the amide -The parent chain is every carbon and N combined -Numbers on the N side are replaced with N -The acid side contains numbers

Carboxylic acid nomenclature

-longest chain must contain the -COOH attachment and it must be carbon 1 -"Oic" and "acid" are the endings -contains an -OH attachment on the end and a bonded "O" attachment -count the points just not the OH's

Aldehydes Nomenclature

-longest chain recieves the ending name "al" -Other attachments are named before the parent chain -No numbering system as the "H" is always AT THE END

Amines nomenclature

-longest chain that the nitrogen is connected to is the parent chain -The N gets lowest number priority -Ending is "amine" -attachments go first but instead of their numbers they are put as a capital N

Branched Ethers

-number where the "O" is first -then the smallest group -add oxy -last is the whole chain (no separation) ex/2-ethoxypentane

Esters Nomenclature

-separated by an "O" also contains a double bonded "O" -Separation starts at the main "O" -ending is "oate" -where ever the double bonded "O" is, that is where the ending"Oate" goes -group without the double bonded "O" GOES FIRST

A

Diastereomer

A stereoisomer based on a double bond, in which different types of atoms or groups are bonded to each carbon in the double bond.

Alcohol

Which grouping has hydrocarbons with a hydroxy group (-OH) attachment

Alcohols

Difference between an aldehyde and a ketone

Aldehydes have the double bond "O" at the end of a molecule and a ketone has the double bond "O" anywhere on the chain except for the end

Which molecule is an example of an organic molecule? A) CO2 B) C2H2 C) CACO3 D) NACN E) CAC2

B

Physical properties of an aldehyde/ketone

BP/MP 4th lowest 4th lowest polarity solubility in polar solvents 4th lowest solubility in non-polar solvents 4th highest LDF D/D

The prefix "phenyl" refers to a(n)

Benzene ring

What is the molecular formula of cyclohexane?

C6H12

What is the formula for hept-1-ene?

C7H14

Which is a general formula for a straight chain or branched chain Alkane? A) C2nHn B) CnHn C) CnH2n+2

CnH2n+2

Isomers are molecules that have....

Different three dimensional structures with the same molecular formula

What results from a reaction between an alcohol and a carboxylic acid?

Ester

Which molecule would you expect to have the lowest bp? A) ethane B) ethene C) propane D)pentyne E) hexane

Ethene

Amides

Formed by the reaction of an amine and a carboxylic acid

Physical properties of carboxylic acids

Alkanes

Hydrocarbons that contain only single bonds, "ane"

Alkenes

Hydrocarbons with one or more double bonds, "ene"

Alkynes

Hydrocarbons with one or more triple bonds, "yne"

In a benzene ring, the carbon to carbon bonds are...

Intermediate length between single and double bonds

Physical properties of hydrocarbons( R ) (anes, enes, ynes, aromatic, cyclos)

Lowest MP/BP Lowest polarity Solubility in polar solvents highest Low reactivity Highest solubility in non-polar solvents LDF

Constitutional isomers

Molecules that have the same molecular formula but their atoms are bonded together in a different sequence

Isomers

Molecules that have the same molecular formula but their atoms are in a different arrangement

Primary Amine

R-NH2, occurs when nitrogen group is only bonded to one atom

Secondary Amine

R2NH, occurs when nitrogen group is bonded to two atoms

Tertiary Amine

R3N, occurs when nitrogen group is bonded to 3 atoms

Stereoisomers

Same formula and basic structure but a different 3D arrangement of atoms

Structural Isomer

Same molecular formula, different structural formula

Benzene

The electrons that participate in the double bonds shared throughout the entire compound. If benzene is a branch, it's called phenyl

Hydrocarbon

compound containing only carbon and hydrocarbon, name has prefix, root, and suffix

Aldehyde

ending is "al"

Amines

organic compounds with an amino group, ending "amine"

what makes something an organic molecule

organic means that a molecule has a carbon backbone with some hydrogen thrown in for good measure. Inorganic molecules are composed of other elements. They can contain hydrogen or carbon, but if they have both, they are organic.

cyclic structure

prefix is cyclo cyclopentane. These are aromatic compounds

-OH is attached to a "C" that is attached to ONE other C

primary alcohol

-OH is attached to a "C" that is attached to TWO other C's

secondary alcohol

-OH is attached to a "C" that is attached to THREE other C's

tertiary alcohol
