Organic Chemistry The study of all compounds containing carbon. Carbon is the basis for life on Earth. This unit will focus on hydrocarbon compounds. Compounds containing only hydrogen and carbon The study of all compounds containing carbon. Carbon is the basis for life on Earth. This unit will focus on hydrocarbon compounds. Compounds containing only hydrogen and carbon

Review How many valence electrons does carbon have? How many bonds does carbon need? How many valence electrons does hydrogen have? How many bonds does hydrogen need? Shapes are predicted by VSEPR theory. Shapes of organic molecules will change as a result of single, double, or triple bonds. Most likely shapes will be tetrahedral, trigonal planar or linear.

Alkanes Hydrocarbons with only single covalent bonds aka - saturated hydrocarbons carbon-carbon bonds are very stable and form chains Ethane - simplest alkane with a carbon-carbon bond - C 2 H 6 Hydrocarbons with only single covalent bonds aka - saturated hydrocarbons carbon-carbon bonds are very stable and form chains Ethane - simplest alkane with a carbon-carbon bond - C 2 H 6

Continuous-chain alkanes Contain any number of atoms in a straight chain. Names will end in -ane Names are given by the International Union of Pure and Applied Chemistry (IUPAC). You need to memorize the 1st ten and their prefix meanings. You will not be allowed to use your periodic table. Contain any number of atoms in a straight chain.
