The Tutor and Student explored the concept of aromaticity, using benzene as a central example. They discussed why aromatic compounds undergo electrophilic substitution rather than addition reactions, the criteria for aromaticity (Hückel's Rule), and common examples. The session also covered nomenclature for substituted benzenes, basicity of aromatic compounds, and introduced electrophilic aromatic substitution reactions.

The student and tutor reviewed the mechanisms of electrophilic addition and free radical addition reactions of alkenes. They specifically delved into Markovnikov's rule and its anti-Markovnikov counterpart, the Kharasch effect, and discussed the conditions under which each occurs. The next session will cover aromatic compounds and their reactivity.

The Student and Tutor reviewed free radical chemistry, focusing on bond dissociation types, the formation and characteristics of free radicals, and their role in alkane halogenation (chlorination and bromination). They discussed reactivity versus selectivity, allylic and benzylic substitution, and began to touch on electrophilic addition reactions in alkenes.

The session focused on methods for synthesizing carboxylic acids, including ozonolysis, nitrile hydrolysis, Grignard reagent reactions, and reactions involving carbon dioxide. The Student learned about carboxylic acid derivatives and their addition-elimination reactions. The next session will cover radical chemistry, including bond cleavages and dissociation energies.

The Tutor and Student discussed nucleophilic addition to conjugated carbonyl compounds, differentiating between 1,2 and 1,4 additions and the influence of nucleophile strength. They then moved on to carboxylic acids, covering nomenclature, acidity trends, and preparation methods via oxidation and ozonolysis. The next class will continue with reactions of nitriles.

The Tutor and Student reviewed the reduction and oxidation reactions of aldehydes and ketones, including specific reagents and outcomes. They then delved into named reactions such as the Baeyer-Villiger oxidation and the Wittig reaction, practicing their mechanisms and product prediction. The next class will cover nucleophilic additions to double bonds and carboxylic acids.
