- carbon - valency and electronic configuration
The atomic number of carbon is 6. Its electronic configuration is 2, 4. It requires,
4 electrons to achieve the inert gas electronic configuration.
- allotropes in carbon- diamond and graphite(difference in physical and chemical properties)
-bonding in carbon (covalnet bond)
• carbon requires 4 electrons to achieve the inert gas electronic configuration. But carbon cannot
form an ionic bond
• It could gain four electrons forming C4- cation. But it would be difficult for the
nucleus with six protons to hold on to ten electrons.
• It could lose four electrons forming C4+ cations. But it requires a large amount
of energy to remove four electrons.
• Thus, carbon overcomes this problem by sharing of its valence electrons with
other carbon atoms or with atoms of other elements.
• The bond formed by mutual sharing of electron pairs between two atoms in a
molecule is known as Covalent Bond
-types of bonds that carbon can form(single , double)
-lewis structures with examples

Chemistry is a very important subject when it comes to deciding careers in medicine, pharmacy or engineering. As a pharmaceutical graduate, I possess special knowledge in chemistry and have been guiding students through making their concepts easier with the chemical reactions and the hardest concept simplified into easier real-life examples.
-Basic chemistry
-Organic chemistry concepts (calculations, chemical reactions, etc)
- Inorganic chemistry (Biochemistry, etc)
-Chemical Reactions (including Grignard reagents, Redox reactions, etc)
-Advanced level (Graduate level)

You only need to share the topic and if you have a specific course overview, please share it with me so that I can help you out in the best possible way to teach you with the same concepts as you have been taught in the school/college/university.

Welcome to university students or masters and doctoral students!!! I teach the course of Natural Products Chemistry or Phytochemistry or Pharmacognosy. In this class we will learn about the methods of extracting, separating and identifying the chemical form of active chemical compounds (biologically active secondary compounds) from natural sources, such as medicinal and aromatic plants. We will also discuss what is known as chromatography, spectroscopy, spectroscopy, mass spectrometry, magnetic resonance and advanced analysis devices used in this field.

This is in addition to knowing some important applications of these active materials in various fields, such as the pharmaceutical industry, agriculture, etc. We will also learn the practical and laboratory methods that are carried out in the laboratory to conduct toxicity, antioxidant, and diabetes analyses, etc.

Experience: About 20 years of practical experience in the field of chemistry, medicinal and aromatic plants and pharmacy with parallel training and private lessons for science and chemistry curricula.

With my qualifications and experience, I hold a master’s degree and a doctorate in organic chemistry (chemistry of natural products), in addition to other graduate degrees and a doctoral scholarship in pharmaceutical sciences in Belgium from the Erasmus Mendus Organization of the European Union.

Organic Chemistry doesn’t have to be memorization overload. It can actually make perfect sense once you gain all the pieces and some intuition. In this class, we’ll focus on why reactions happen, not just what happens.
We’ll start with the basics — structure, acid-base behavior, resonance, and stability — then move into core reaction types like electrophilic addition (alkenes and alkynes), nucleophilic substitution and elimination, electrophilic aromatic substitution (EAS), reductions, oxidations, and aldol reactions.
You’ll learn to see patterns, predict mechanisms, and connect topics intuitively, so you can stop memorizing and start understanding. My goal is to make organic chemistry feel like solving a puzzle — once you know the rules, the pieces start to fit perfectly.

I just love making chemistry click for you. I'll turn every difficult concept into a story you will remember lifetime. My students go from “I’m doomed” to crushing tests with better scores. Learning is fun... You just need a teacher who refuses to let it be anything else. I guarantee you better results.

Course Description: This is a comprehensive, two-semester sequence that introduces the fundamental principles of chemistry necessary for all science, engineering, and pre-health majors. Topics include stoichiometry, gas laws, atomic and molecular structure, chemical bonding, thermochemistry, and the states of matter. The second semester focuses on chemical kinetics, equilibrium (acid-base and solubility), thermodynamics ($\Delta G, \Delta H, \Delta S$), electrochemistry, and an introduction to nuclear and coordination chemistry. The accompanying laboratory emphasizes quantitative analysis and safe, precise experimental technique.Learning Outcomes: Students will be able to perform stoichiometric calculations, predict molecular geometry, apply equilibrium principles to problem-solving, and interpret chemical data accurately.
