Study Notes

Inorganic Compounds

Soluble in water, acting as a polar solvent.
Generally composed of a mix of metals and nonmetals.
Comprise ionic or polar covalent bonds.
Typically have high melting and boiling points.
Usually lack distinct odors and are not flammable.

Organic Compounds

Not soluble in water; soluble in nonpolar solvents.
Composed mainly of carbon (C) and hydrogen (H), with possible inclusions of oxygen (O), sulfur (S), nitrogen (N), fluorine (F), chlorine (Cl), bromine (Br), or iodine (I).
Mainly formed through covalent bonds.
Characterized by low melting and boiling points.
Often have strong distinct odors and are flammable.

Hydrocarbons

Consist exclusively of carbon and hydrogen atoms.
Include categories such as alkanes, alkenes, alkynes, and aromatic compounds.

Alkanes

Examples: Methane, Ethane, Propane, Butane, Pentane, Hexane, Heptane, Octane, Nonane, Decane.
Known as saturated hydrocarbons, containing only single bonds between carbon atoms.

Isomers of Alkanes

Example: 2-Methylpropane has three carbons in the main chain, with a branch off the second carbon.

Cycloalkanes

Formed in cyclic or ring structures, maintaining a skeletal shape.

Haloalkanes

Halogen atoms (e.g., chlorine, bromine) replace one or more hydrogen atoms in alkanes or cycloalkanes.

Functional Groups

Define organic families with specific structural features; vital for classifying organic compounds.

Alkenes and Alkynes

Alkenes: Contains a double bond (H2C=CH2).
Alkynes: Contains a triple bond (HC≡CH).

Alcohols and Ethers

Both contain oxygen; alcohols have a hydroxyl group (-OH), while ethers consist of an oxygen connected to two carbon atoms.

Carbonyl Group

Central in aldehydes and ketones, characterized by a carbon-oxygen double bond.
Aldehydes bond the carbonyl carbon to at least one hydrogen atom.
Ketones bond the carbonyl carbon to two other carbon atoms.

Carboxylic Acids and Esters

Both include the carboxyl functional group, combining carbonyl and hydroxyl groups.
Carboxylic acids have a hydroxyl group bonded to a hydrogen atom.
Esters have the oxygen bonded to a carbon atom instead of a hydrogen.

Amines and Amides

Contain nitrogen, with amines having carbon groups bonded to the nitrogen atom.
Amides feature a nitrogen group replacing the hydroxyl group in carboxylic acids.
