Chirani Your chemistry tutor

I am Chirani Thammita Lennon who is an experience chemistry tutor for nearly a decade. I an experienced in guiding high school and college students with any needs through the guidance to make chemistry an enjoyable subject. I specialize in subjects like biochemistry, organic chemistry, atomic structure, and more in depth knowledge on the lab skills. Grasping complex concepts in chemistry is nothing to do with your knowledge but the way you approach it. Make chemistry a story, game or a fantasy novel. You just need to know the easy tricks all chemists use to gain their success. That’s where I come to play. I excel in covering all bases that is needed for you to excel in homework, lab assignments, group work and assignments that get You points and bonus points. Grades will be nice but understanding the concepts of chemistry is more important. Make sure you are comfortable with this “hard” subject!

Chemistry class overview

My tutoring style structured, patient, interactive, and engaging, focusing on hands on learning experiences. I specialize in teaching chemistry in all sub groups such as states of , acid, bases and pH. It doesn’t matter if you want help in general chemistry or organic chemistry, i will help you succeed by making you understand the concept with the technique you prefer. Everyone studies and retain information different, spring feel afraid to reach out to tell me what you are compatible and comfortable with. My teaching techniques all include presentations, diagrams, note taking, color coding and many more. The most important method of teaching is communication. I like when You can contact me when you have any questions about any material we covered or any material you don’t understand but needs ur get help with. Therefore, let’s navigate chemistry together!

Chemistry concepts taught by Chirani

Student learned 3 days ago

The class began by reviewing the Student's homework on quantum numbers, which the Student completed successfully. The main academic focus was on SN1, SN2, E1, and E2 reactions, where the Student practiced identifying reaction types and products, leading to a deeper understanding of Zaitsev and Hoffman elimination rules. Additionally, the class introduced and explained the rules for drawing resonance structures, with practical drawing exercises. For follow-up, the Student was assigned homework on drawing resonance structures and further practice questions for SN1/SN2/E1/E2 reactions, and a new Open Stacks textbook was discussed as a resource for future learning.

The Student and Tutor reviewed homework on isomer identification, including enantiomers and diastereomers. They then covered fundamental General Chemistry topics such as quantum numbers and molecular orbitals, before progressing to Organic Chemistry concepts like sigma and pi bonds, hybridization, and resonance. The Student received new practice questions on quantum numbers for homework and agreed to a revised schedule for upcoming sessions.

The Student and Tutor reviewed various types of isomers in Organic Chemistry, including structural, stereoisomers (conformational and configurational), enantiomers, diastereomers, and meso compounds, along with their respective nomenclature (R/S, cis/trans). The Student actively practiced drawing molecular structures and identifying the relationships between different compounds through a series of practice questions. For homework, the Student was assigned additional practice questions focusing on drawing structures, identifying isomer relationships, and reasoning behind those classifications. They also scheduled future sessions to cover bonding and acids/bases.

Isomers: Structural vs. Stereoisomers

Conformational Isomers

Configurational Isomers: Enantiomers

Configurational Isomers: Diastereomers

Meso Compounds

Student learned 12 days ago

The Student and Tutor engaged in a comprehensive lecture on isomers in organic chemistry. They covered structural and stereoisomers, delving into conformational isomers (Newman projections, cyclic conformations) and configurational isomers (enantiomers, diastereomers, chirality, meso compounds). The session concluded with a discussion on assigning R/S configurations. As homework, the Student was encouraged to review the material, explain the isomer tree to the Tutor in the next session, and practice problems from Khan Academy to solidify understanding.

R/S Configuration & Fisher Projections

Diastereomers & Miso Compounds

Enantiomers & Optical Activity

Conformational Isomers: Newman Projections & Cyclic Alkanes

The Student and Tutor engaged in extensive practice of organic chemistry nomenclature, working through 50 complex naming problems across various functional groups and structures. They identified common errors related to carbon chain counting and functional group identification, and reviewed the principles of drawing compounds. The next sessions are planned to cover isomers and isomer practice questions.

Student and Tutor reviewed General Chemistry 1 concepts, including periodic trends, bonding types, molecular geometry, and polarity, by going through a practice packet. The session also introduced the concept of hydrogen bonding and the unique properties of Xenon. They scheduled the next two sessions to complete the Gen Chem 1 review and prepare to begin Gen Chem 2 topics, starting with colloids.

Periodic Trends: Atomic Radius & Ionization Energy

Chemical Bonds: Ionic

Covalent & Polarity

Hydrogen Bonding: Unique Intermolecular Interactions

Lewis Structures

Formal Charge & Resonance

VSEPR Theory: Molecular Geometry & Polarity

Noble Gas Exceptions: The Case of Xenon's Reactivity
