Tips to Studying Organic Chemistry

Slide 4: 

Modern Definition of Organic Chemistry Organic chemistry involves the study of the structure, properties, composition, reactions, and preparation (by synthesis or by other means) of chemical compounds consisting primarily of carbon and hydrogen, which may contain any number of other elements, including nitrogen, oxygen, the halogens as well as phosphorus, silicon and sulfur.

Comparison Between Organic and Inorganic Compounds

Slide 12: 

Organic Compounds have covalent bonds. have low melting points. have low boiling points. are flammable. are soluble in nonpolar solvents. are not soluble in water. are nonconductors of electricity Inorganic Compounds have ionic bonds. have high melting points. have high boiling points. are nonflammable. are soluble in polar solvents. are soluble in water. are conductors of electricity Comparison Between Organic and Inorganic Compounds

Slide 30: 

Ways of Representing Organic Compounds Molecular Formula tells the kind and number of each type of atom in a molecule but does not show the bonding pattern. Structural Formula shows each atom and bond in a molecule Condensed Structural Formula shows all the atoms in a molecule in sequential order indicating which atoms are bonded to which Line Formula (Carbon Skeleton Formula) assumes a carbon atom at any location where lines intersect - Assume a carbon at the end of any line - Each carbon in the structure is bonded to the correct number of hydrogen atoms Butane C4H10

Slide 31: 

Ways of Representing Organic Compounds Ball and Stick Model have the balls represent the relative sizes of the atoms and the sticks represent the covalent bonds between atoms Space-filling Model shows how much space an atom (or molecule) really occupies.
