Hybridization Practice Finish the Hybridization Practice sheet. We will review selected problems as a class.

Naming Organic Compounds

Hydrocarbons Simplest organic compounds Bonds involving Carbon and Hydrogen Saturated Hydrocarbon – all single bonds Unsaturated Hydrocarbon – multiple bonds (single, double triple)

Alkanes Saturated hydrocarbons Formula: Cn. H 2 n+2 Condensed Structural vs. Expanded Structural Formulas

Prefixes for organic groups

Rules for Naming Hydrocarbons 1. Find the longest continuous chain of carbon atoms. Use the proper prefix to name the chain. If it is an alkane add the ending –ane If it is an alkene add the ending –ene If it is an alkyne add the ending -yne 2. Number the carbon atoms in the chain so that the lowest possible numbers will be given for the attached hydrocarbon groups 3. Name the groups attached to the chain by adding a prefix –yl to the stem name. Locate them by identifying the number assigned to the carbon it is located on 4. If there is more than one group arrange them in alphabetical order

Complete problems 1, 2, 3 on a sheet of paper We will review selected responses as a class by drawing the structure or writing the name on the board.

Alkenes Unsaturated compounds with at least one double bond Cn. H 2 n Use the suffix –ene in naming Position of the double bond is indicated using the lower number of the two carbon atoms that the double bond joins

Alkynes Unsaturated compound with at least 1 triple bond Cn. H 2 n-2 Use the suffix –yne in naming Number the triple bond using the lowest number carbon

Halogen Substitution A hydrogen can be replaced with Chloro -Cl Bromo -Br Iodo -I Name using the lowest number carbon
