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 2 days ago

The Student provided an update on their recent chemistry exam and discussed the upcoming group project for their biology class. The Tutor and Student then initiated a new chemistry unit on bonding, covering ionic and covalent bonds, electronegativity, formal charge calculations, and an introduction to VSEPR theory. They scheduled the next session to delve into more advanced theories of covalent bonding.

Ionic and Covalent Bonding Basics

Electronegativity and Bond Polarity

Lewis Structures and the Octet Rule

Formal Charge Calculation

Bond Strength and Enthalpy

VSEPR Theory and Molecular Geometry

The Student and Tutor continued their piano lesson, focusing on improving the Student's performance of "Ode to Joy" by addressing timing, note accuracy, and chord holding techniques. They then introduced a new piece, "Waltz in A minor," with the Student beginning to learn its right-hand melody and counting. Homework includes practicing "Ode to Joy" slowly with precise counting and mastering the first two lines of "Waltz in A minor."

The session focused on Organic Chemistry, specifically on aldehydes and ketones. The Tutor instructed the Student on naming conventions, preparation methods, oxidation, and seven different nucleophilic addition reactions, including their mechanisms and key differences. The Student practiced applying these concepts by working through a series of 15 practice questions. The next session is planned to cover carboxylic acids and related reaction mechanisms.

Aldehydes & Ketones: Structure

The Tutor and Student reviewed core concepts in thermochemistry, including definitions of energy, thermal energy, temperature, and heat, along with the Law of Conservation of Energy and phase changes. They delved into enthalpy, practicing calculations, understanding Hess's Law, and defining standard enthalpies of combustion and formation. The session concluded with an introduction to Gibbs free energy, its relationship with spontaneity, and practice problems. For the next session, they plan to cover reaction mechanisms and alkyl halides, followed by a general review and practice questions on Thursday.
