Study Notes
Basics of Organic Chemistry
- Organic chemistry studies the structure, properties, and reactions of organic molecules.
- Organic molecules contain carbon atoms covalently linked with hydrogen, oxygen, or nitrogen atoms.
- Carbon-carbon or carbon-hydrogen bonds in general define organic compounds, but some exceptions exist: carbonates, cyanides, and CO2.
-
Aliphatic compounds have open chains, branched chains, or unbranched chains. These include alkanes, alkenes, alkynes, and their derivatives.
- Saturated Aliphatic Compounds contain only single bonds (e.g., alkanes).
- Unsaturated Aliphatic Compounds contain double or triple bonds (e.g., alkenes, alkynes).
- Alicyclic compounds have carbon atoms arranged in rings. (e.g., cycloalkanes).
- Aromatic compounds have a ring with alternating single and double bonds.
- Hydrocarbons contain only carbon and hydrogen. Examples include alkanes, alkenes, alkynes, and aromatic hydrocarbons.
Functional Groups
- Functional groups are specific collections of atoms that react in predictable ways.
- Examples include: hydroxyl (-OH), carboxyl (-COOH), aldehyde (-CHO), ketone (C=O), amine (-NH2), and ether (R-O-R).
- Each functional group has a unique structure and affects the molecule.
- Alkanes are the only class without a functional group. Alkenes double bond acts as the functional group.
Naming Organic Compounds
- The IUPAC rules are used for naming organic compounds.
- The base name relates to the number of carbon atoms in the main chain/parent chain which is the longest continuous carbon chain.
- The suffix reflects the functional group.
- Substituents are groups attached to the parent chain.
- In cyclic hydrocarbons, the prefix cyclo- is added before the base name (e.g., cyclohexane).
Naming Organic Compounds Steps
- Identify the Parent Chain: Determine the longest continuous chain in the molecule.
- Number the Parent Chain: Number carbons starting from the end closest to a substituent, resulting in the lowest possible numbers for substituents.
-
Naming Substituents: Idenfy substituents, like alkyl groups or functional groups (e.g., -OH, -C=O).
- Use prefixes (di-, tri-, tetra-) for multiple of the same substituent.
-
Assigning Locants: Use numbers to indicate the positions of substituents on the main chain.
- Assign the lowest possible numbers, considering alphabetical order for multiple groups.
-
Naming Functional Groups: Identify and name the main functional group with highest priority. This determines the suffix of the compound's name.
- "-ol" for alcohols, "-one" for ketones, "-oic acid" for carboxylic acid.
- Putting It All Together: Combine names of the parent chain, substituents and functional group, separated by hyphens and commas when necessary.
Applications of Organic Chemicals
- Used in the production of medicine, soaps, shampoos, powders, and perfumes.
- Various fuels like natural gas and petroleum are organic compounds.
- Many fabrics used for clothing are made from organic compounds.
Types of Organic Reactions
- Addition Reactions: Atoms are added to a molecule, often across a double or triple bond.
- Substitution Reactions: One atom or group is replaced by another.
- Elimination Reactions: Atoms or groups are removed from a molecule, often forming a double or triple bond.
- Condensation Reactions: Two molecules combine, eliminating a small molecule like water.
- Oxidation-Reduction Reactions: Involve the transfer of electrons, where one molecule loses electrons (oxidation) and another gains electrons (reduction).
Hybridization of the Carbon Atom and Shapes of Organic Molecules
- Hybridization explains the bonding in organic compounds.
- sp3 Hybridization: Carbon combines one 2s and three 2p orbitals forming four equivalent sp3 orbitals. This leads to a tetrahedral geometry with bond angles of 109.5 degrees. (e.g., methane)
- sp2 Hybridization: Carbon combines one 2s and two 2p orbitals, forming three equivalent sp2 orbitals. This leads to a planar geometry with bond angles of 120 degrees. (e.g., ethene)
- sp Hybridization: Carbon combines one 2s and one 2p orbital, forming two equivalent sp orbitals. This leads to a linear geometry with bond angles of 180 degrees. (e.g., ethyne)
