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 1 day ago

Student and Tutor completed a detailed practice exam covering various topics including quantum numbers, energy calculations, electron affinity, formal charge, resonance, bond angles, intermolecular forces, and heat calculations. They thoroughly reviewed specific problem areas like nodes in atomic orbitals and clarified several conceptual points. The upcoming session will focus on a new practice paper designed around Lewis structures, formal charge, intermolecular forces, and general bonding.

Heat Calculations: Phase Changes and Temperature Shifts

Bond Angles in Cyclic Hydrocarbons

Electron Affinity and Exothermic Reactions

Particle-Wave Duality: Wavelength and Momentum

Nodes in Atomic Orbitals

The Tutor introduced stoichiometry, including its steps and rules, but pivoted to other topics when the Student indicated it had not yet been covered in their school curriculum. They then discussed various types of chemical reactions, their products, and the fundamental rules for balancing chemical equations, emphasizing the difference between coefficients and subscripts. The session concluded with the Student practicing balancing several chemical equations, with plans to continue this practice and begin discussing bonding in the next session.

Balancing Chemical Equations: The Golden Rules

Understanding Chemical Reaction Types

Coefficients vs. Subscripts: The 'Dad and Kid' Analogy

Introduction to the Mole Concept (n = m/MW)

The Student and Tutor reviewed phase transitions, including vaporization, condensation, melting, and freezing, emphasizing the concept of dynamic equilibrium. They defined boiling point and normal boiling point, practiced calculating total heat for phase changes using specific formulas, and explored the characteristics and types of crystalline solids. The next session will focus on exam preparation covering various topics including advanced bonding and solids/liquids.

The Student and Tutor reviewed various Chemistry concepts, including unit conversions, scientific notation, temperature scales, density, and a range of gas laws (Boyle's, Charles's, Gay-Lussac's, Ideal, and Combined). They practiced solving numerous problems applying these laws and focused on common pitfalls, particularly the conversion of Celsius to Kelvin. The next session was scheduled for tomorrow to cover stoichiometry.

The Student and Tutor reviewed key concepts in general chemistry, focusing on intermolecular forces and properties of liquids. They covered topics such as molecular states of matter, dispersion forces, hydrogen bonding, viscosity, cohesion, adhesion, and surface tension. The session concluded with an introduction to phase diagrams and their interpretation, with plans to continue with phase transitions and solid-state matter in the next class.

The session focused on core organic chemistry concepts related to alkenes, including their structure, stability, and reaction mechanisms (SN1, SN2, E1, E2). The Student and Tutor explored electrophilic addition reactions, Markovnikov's rule, Hammond's Postulate, and carbocation rearrangements like hydride and methyl shifts. They also covered specific reactions such as halogenation and halohydrine formation. Additionally, the discussion extended to MCAT preparation strategies, essential prerequisite courses, and advice on choosing a major for medical school applications. For homework, the Student was assigned practice questions on alkene addition reactions, halogenation, and halohydrine formation.
