Objective  Today I will be able to:  Apply hybridization to determining the orbital shape  Apply naming rules to naming organic compounds

Homework  STEM Fair Presentations – January 23  Finish Organic Compounds Naming Practice

Agenda  Warm – Up  Hybridization Practice  Review Practice  Organic Chemistry Notes  Organic Chemistry Naming Practice  Exit Ticket

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: C n H 2n+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

Alkenes  Unsaturated compounds with at least one double bond  C n H 2n  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  C n H 2n-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

Exit Ticket  What is the structure of:  5-butyl-3,7-diethyl-2,8-dimethyl-4,6-dipropyl-1,8-nonadiene
