16 Organic Chemistry Flashcards
Hydrocarbons:
Hydrocarbons are compounds that contain
only carbon and hydrogen
Alkanes
Alkanes are hydrocarbons that contain
only single bonds. They are also known as saturated hydrocarbons.
Alkane(CnH2n+2)
Methane CH4
Ethane C2H6
Propane C3H8
Butance C4H10
Pentane C5H12
Alkenes
Alkenes are hydrocarbons that contain
double bonds. The are examples of unsaturated hydrocarbons.
Alkene (CnH2n)
Ethene (ethylene) C2H4
Propene C3H6
Butene C4H8
Pentene C5H10
Alkynes
Alkynes are hydrocarbons that contain
triple bonds. The are also examples of unsaturated hydrocarbons.
Alkynes (CnH2n-2)
Ethyne C2H2
Propyne C3H4
Butyne C4H6
Pentyne C5H8
Hydrocarbon Rings
Many Hydrocarbons form fings instead of chains. One of the most important of these compounds is the aromatic hydrocarbons, the simplest of which is
aromatic hydrocarbons, the simplest of which is
benzene, C6H6
Alcohols
Alcohols are organic compounds in which a hydrogen has been replaced with a
hydroxyl group (OH)
This makes alcohols polar, and enables them to form hydrogen bonds.
Methanol CH3OH
Ethanol C2H5OH
Propanol C3H7OH
R - OH
Organic Acids
Organic Acids are organic compounds in which a hydrogen has been replaced with a
carboxyl group (COOH)
Methanoic Acid HCOOH
Ethanoic (Acetic ) Acid CH3COOH
Propanoic Acid C2H5COOH
O
R - C - OH
(Double Bond between C and O)
Halides
Halides are organic compounds in which one or more hydrogen have been replaced with a
halide (F, Cl, Br, I)
Chloromethane CH3Cl
Chloroethane C2H5Cl
Chloropropane C3H7Cl
Amines
In an amine, a hydrogen atom has been replaced by an
amino group (NH2)
Aminomethane (Methyl amine) CH3NH2
Aminoethane (Ethyl amine) C2H5NH2
Aminopropane (Propyl amine) C3H7NH2
Aldehydes
An aldehyde contains a
carbonyl group (C=O) connected to at least one hydrogen atom.
Methanal (Formaldehyde) HCHO
Ethanal CH3CHO
Propanal C2H5CHO
O
R - C - H
(C and O double bonded)
Ketones
A ketone is similar to an aldehyde in that it also contains a carbonyl group (C=O), but in a ketone, the carbon in the carbonyl group is
not connected to any hydrogen atoms.
Propanone C3H6O
Butanone C4H8O
Pentanone C5H10O
O
R - C - R
(C and O double bonded)
Ethers
In an ether, an oxygen atom serves as a link in a hydrocarbon chain. The name of an either is determined by
the lengths of the chains on either side of oxygen.
Methoxymethane (Dimethyl ether) CH3OCH3
Methoxyethane (Methyl ethyl ether) CH3OC2H5
Methoxybutane (Methyl Butyl ether) CH3OC4H9
Ethoxypropane (Ethyl Propyl ether) C2H5OC3H7
R - O - R
Esters
In an ester, an ester group (COO) serves as a link in a hydrocarbon chain. An ester is formed in a reaction between an alcohol and an organic adic, and its name is derived from these reactants.
Methyl methanoate HCOOCH3
Methyl ethanoate CH3COOCH3
Methyl Propanoate C2H5COOCH3
O
R - C - O - R
(double bond betweenn c and upper O)
Isomers
Two or more molecules with the same molecular formula, but with
different arrangements of atoms and different chemical properties.
Addition
In an addition reaction, a carbon-carbon double bond is broken down into a single bond,
freeing each of the two carbons to bond with another element. In the same way, a triple bond can be converted into a double bond in an addition reaction.
