- Be able to correctly draw and label a reaction coordinate diagram for a substitution reaction.
- Be able to draw mechanism arrows on a given substitution reaction and label the nucleophile and leaving group.
- Be able to describe the key characteristics that make a leaving group GOOD and rank leaving groups in terms of their ability to leave.
- Be able to name an alkyl halide using the IUPAC sysem, and be able to draw an alkyl halide from its name.
- Be able to identify some specific alkyl halides based on their common names (see slide 7-8)
- Be able to identify primary, secondary, and tertiary alkyl halides and be able to identify the alpha, beta, gamma, and delta carbons on the alkyl chain of an alkyl halide.
