  1. Organic vs Inorganic Compounds OrganicInorganic Carbon always Carbon may present be present Covalent Ionic bonds bonds mostly mostly Some soluble Most soluble in H2O in H2O

  2. Organic vs Inorganic Compounds OrganicInorganic In H2O Non- Conductors conductors in H2O Usually Usually do not combustible combust Solid, Liquid & Mostly solids gases common

  3. What makes Carbon so special? • forms bonds with other carbon atoms readily • forms single, double, triple bonds to carbon • forms long chains and rings • found in all living organisms

  4. Representing compounds molecular formula: C3H8. => no info about structure Lewis dot formula: H H H => gets messy H••C••C••C••H H H H •• •• •• •• •• ••

  5. Structural formula: H H H => can get busy H-C-C-C-H looking H H H Condensed structural formula: CH3CH2CH3 or H3CCH2CH3 or CH3-CH2-CH3.

  6. The interesting problem of isomers Different compounds with the same formula are isomers. Example; C2H6O can be CH3-CH2-OH ethyl alcohol or CH3-O-CH3 methyl ether

  7. All isomers are different compounds of same formula. There are several kinds of isomers. The first kind we examine are constitutional or structural isomers have a different sequence and kinds of bonds between the atoms, as for ethyl alcohol & methyl ether.

  8. Functional Groups... are groups of atoms, bonded in a particular way, that act as a unit having characteristic chemical reactions.

  9. Functional groups often contain polar covalent bonds. Some examples of functional groups: alkene C=C alkyne C C alcohol C-OH ether C-O-C amine C-N

  10. Hydrocarbons contain only C, H 4 types of hydrocarbons alkanes: contain C-C only alkenes: contain C=C alkynes: contain C C aromatic: contain 6-carbon ring, alternating C=C and C-C

  11. Examples of hydrocarbons alkane: CH3-CH2-CH2-CH3 alkene: H2C=CH-CH2-CH3 alkyne:H-C C-CH2-CH3 aromatic:

  12. Alkanes have all carbons: * with 4 single bonds; * 109° bond angles.
