Kelechi Your chemistry tutor
I'm Kelechi Chioma, A Biology and Chemistry tutor with over 24 years of experience. I hold a Bachelor's degree in Biochemistry. My Specialties include tailor-made learning approach, Exam focus teaching, and real world application of concepts. I work with student across all strata including primary, secondary and tertiary levels. I provide engaging sessions to enhance understanding. For students with special needs, I ensure a supportive and inclusive learning environment. I encourage a lot of questioning and practice especially of past exam papers. I push students to also study on their own. devoting study habits and methods for students and learners. I source for the best materials whether online or offline that will help students grasps the concepts better and quicker. Learners are motivated. Lets ace Biology and chemistry together.
Kelechi graduated from Nnamdi Azikiwe University

Chemistry class overview
My tutoring method is interactive, engaging and exam focused, providing personalised tutoring in various chemistry subjects like Chemical bonding, Organic Chemistry and many more. I use a blend of of tech tools, like online collaboration platforms, digital simulations and interactions. I make learning dynamic and hands-on. Following a structured curriculum, I ensure students grasp the complex concepts through a mix of theory and practical applications. I know how to make the hard things simple and explain the complicated aspects of each topic. With over 500 students thought both online and physical I bring to bear over 24 years teaching experience. my hands-on teaching style ensures the deep understanding of the subjects, leading to improved academic performance and exam success. Leaving my students with subject knowledge they will use for a life time.

Chemistry concepts taught by Kelechi
The Student and Tutor engaged in a detailed review of concepts related to chemical bonding and molecular structure, focusing on electron delocalization, resonance, conjugation, and electronegativity. They practiced identifying polar bonds and molecules and calculating bond order. The session involved solving various practice problems to reinforce these topics.
Electron Delocalization and Resonance
Conjugation and Pi Bonds
Electronegativity and Polarity
The class covered stoichiometry, including calculating limiting reactants, moles of products, masses of reactants and products, and percent yield. The student practiced solving problems involving balanced chemical equations, mole ratios, molar masses, and conversions between mass and moles, as well as density calculations. The next session will continue these topics, potentially with new material.
Percent Yield Calculation
Density and its Application in Stoichiometry
Stoichiometric Calculations: Mass-to-Mass
Limiting Reactant Calculation
The tutor and student reviewed electron delocalization and pi conjugation, focusing on their application to molecules like ozone and nitrate. They practiced identifying resonance structures, determining bond orders and hybridization, and applying these concepts to solve example problems, with plans to cover acidity and reactivity in future sessions.
Electron Delocalization
Pi Conjugation
Resonance and Resonance Structures
Hybridization and Unhybridized p Orbitals
The student and tutor reviewed several chemistry topics including periodic trends (atomic size), effective nuclear charge calculation, and redox reactions. They practiced balancing chemical equations, determining limiting reactants through mole calculations, and understanding oxidation states. The session concluded with a plan to continue exploring stoichiometry and limiting reactants in future sessions.
Effective Nuclear Charge (Zeff)
Atomic Size Trends
Ionization Energy
Oxidation and Reduction (Redox Reactions)
Limiting Reactants
The Tutor and Student reviewed Valence Bond Theory, focusing on orbital overlap, hybridization (sp3, sp2, sp), and the distinction between sigma and pi bonds. They practiced identifying hybridization, counting sigma/pi bonds in molecules like CO2 and C2H4, and discussing rotation and isomerism in single versus double bonds. Future practice on complex molecular structures was planned.
Valence Bond Theory
Hybridization
Sigma (σ) and Pi (π) Bonds
Bond Strength and Bond Length
The student worked with the tutor on a set of organic chemistry practice exam questions. They reviewed concepts such as spectroscopy, stereochemistry, isomerism, and nomenclature, practicing problem-solving techniques for various question types. The session concluded with a plan to continue reviewing challenging topics in future meetings.
Stereoisomers and Stereocenters
NMR Spectroscopy: Distinguishing Compounds
Bond Strength and Factors Affecting It
