Robert and Katie delved into the practical aspects of chemistry, specifically molarity calculations and solution preparation. Katie diligently worked through a worksheet, honing her skills in molar mass calculations and converting between grams and moles. They also covered the nuances of preparing solutions using ratios and percentages. The pair concluded their productive lesson by arranging a follow-up to tackle another worksheet.

Robert reviewed epoxide openings, reaction mechanisms, and retrosynthesis with a student from Bradley University in Peoria. They worked through practice problems involving epoxide reactions, multi-step synthesis, and identifying reagents for specific transformations. The learner, who has an exam tomorrow, received guidance on key concepts and strategies for approaching synthesis problems.

During an organic chemistry lesson, a student from Chaffey College in Rancho Cucamonga worked through a series of practice problems. The topics covered included Diels-Alder reactions, reductions, oxidations, electrophilic additions to conjugated dienes, Williamson ether synthesis, epoxide formation, retrosynthesis, and Grignard reagents. Molecular orbital theory was also briefly discussed. For the next lesson, the focus will be on reaction mechanisms.

A challenging organic chemistry homework assignment was the focus of a recent lesson, covering multi-step synthesis problems, SN1/SN2/E1/E2 reactions, Diels-Alder reactions, and the strategic use of various reagents. Complex reaction mechanisms were analyzed, and the importance of considering factors like steric hindrance and protecting groups was discussed. Follow-up lessons were scheduled to continue preparing for the upcoming exam at Ramapo College of New Jersey.

Robert and a student from Green Hope High School in Cary reviewed mass spectrometry and IR spectroscopy, focusing on identifying functional groups and interpreting spectra. They also worked through quiz problems involving reaction mechanisms, including catalytic hydrogenation, anti-dihydroxylation, epoxide formation, and oxidative cleavage of alkenes and alkynes. The learner is to review reaction mechanisms from chapters 8, 9, 12, and 13 and will schedule the next lesson for the week of September 19th.

Robert and Mary-Walter collaborated on a challenging problem set in organic synthesis, delving into various reactions such as bromination, elimination, nucleophilic substitution, and radical reactions. Mary-Walter noted specific questions regarding NBS usage and stereochemistry that she intends to discuss with her professor. They arranged a follow-up lesson for the following day to continue their work and also planned a weekend meeting to prepare for their upcoming organic chemistry exam.
