Expert School Science Tutor with a Passion for Health and Earth Sciences Mastery

Aashima and Iliana reviewed reactions of carboxylic acids and alcohols, including halogenation, anhydride formation, combustion, dehydration, substitution, and oxidation. They then focused on esterification (alcohol + carboxylic acid -> ester) and saponification (base hydrolysis of esters -> soap + glycerol). They discussed the chemistry of soap formation from triglycerides and strong bases, the structure of soap molecules (hydrophobic tail, hydrophilic head), and how soap cleans by forming micelles that trap grease and allow it to be washed away. Finally, they touched on the limitations of soap in hard water and the advantages of detergents. Aashima requested a picture of the PowerPoint slide summarizing the learning goals: soap structure, formation, and cleaning action.

Aashima and Iliana reviewed organic chemistry, focusing on the properties and reactions of esters, amines, haloalkanes, alkenes, alkynes, amides, and carboxylic acids. Aashima explained concepts like polarity, hydrogen bonding, boiling points, solubility, and reactivity, including specific reactions like hydrolysis, esterification, elimination, and electrophilic addition. They plan to cover alcohols, carboxylic acids, esterification, saponification, soaps, and polymers in their next session.

Aashima Sharma tutored Iliana Diamandis on organic chemistry, covering functional group priorities, properties (polarity, hydrogen bonding, acidity/basicity, reactivity), and specific functional groups (alcohols, carboxylic acids, aldehydes, ketones, esters). They discussed reaction mechanisms like oxidation, reduction, esterification, hydrolysis, and transesterification. Iliana will review the material and send questions before the next session.

Aashima is teaching Iliana IUPAC nomenclature for organic chemistry, focusing on functional groups and their naming conventions. They cover hydrocarbons, alcohols, carboxylic acids, esters, and other functional groups, discussing prefixes, suffixes, word roots, and the priority order for naming principal and subsidiary groups. They specifically delve into naming carboxylic acids and esters, and plan to cover more functional groups and reactivity in future sessions.

Iliana is tutored by Aashima on electrolysis, redox reactions, and corrosion in preparation for an exam. They cover factors influencing electrolysis (electrochemical potential, concentration, electrode type), competition between species at electrodes (water vs. ions), and corrosion, particularly rusting of iron. They also discuss corrosion prevention methods, oxidation numbers, oxidizing/reducing agents, and balancing redox reactions. Iliana clarifies her understanding of key concepts like inert vs. active electrodes.

Aashima tutored Iliana on electrolysis and electrochemistry, covering electrolysis principles versus galvanic cells and applications like metal extraction, electroplating, and electrorefining. They discussed electrolysis of molten NaCl and water, and the importance of standard reduction potentials. They plan another session before Iliana's test, potentially focusing on primary and secondary cells.
