Featured Golden Rule of Chemistry: 2. Five- and six-membered rings are the most stable. 

1. Warning: Students often confuse keto-enol equilibria (these are two different species, with a proton moving between them) and the contributing structures for enolates (both structures represent one single species that is the hybrid of the contributing structures) because of structural similarities.

2. Diazomethane converts carboxylic acids into methyl esters in very high yield.

3. The haloform reaction converts methyl ketones into carboxylic acids, breaking a carbon-carbon bond in the process. The haloform reaction is important because it combines an enolate reaction with Mechanism B, both of which are important moving forward.

4. The important carboxylic acid derivatives are acid chlorides, anhydrides, esters, and amides.

Homework:

Read: Sections 18.3-18.4 in the ebook textbook. This text is part of the Longhorn Textbook access program.

Best of luck on the exam, there are no new homeworks or Daily Quizzes this week.
