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!
Chirani graduated from PennWest University Edinboro

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
The student and tutor worked through numerous practice problems identifying SN1, SN2, E1, and E2 reaction mechanisms. They detailed the five-step process for determining reaction outcomes and discussed the specific roles of solvents, bases, and heat. The next session will continue with SN1/SN2 reactions, alcohols, and solvent analysis, with a focus on practice-based learning.
SN1 and SN2 Reactions
E1 and E2 Reactions
Factors Determining Reaction Mechanisms (SN1
SN2
E1
E2)
Carbocation Rearrangements
The student and tutor worked through various chemistry problems related to unit conversions, energy calculations, de Broglie's equation, and the Rydberg equation. They practiced applying formulas and reviewed strategies for approaching exam questions, including unit conversions and the use of constants. The next session will cover periodic trends and electron configurations.
Unit Conversions and Dimensional Analysis
Energy
Frequency
and Wavelength (E=hf
c=λf)
Rydberg Equation for Atomic Transitions
De Broglie Wavelength (λ = h/p)
The tutor and student reviewed IR spectra and then extensively covered the interpretation of H-NMR spectra, including shielding, deshielding, and splitting patterns. They also practiced identifying and predicting products for SN1, SN2, E1, and E2 reactions. The next session will focus on more H-NMR and substitution/elimination reactions.
