Chimica

Pericyclic Reactions (Peri mean around and cyclic mean circle) So, Pericyclic mean around the circle. It may be define as: “A pericyclic reaction is a concerted reaction that proceeds through a cyclic transition state.” Characteristics of pericyclic all reactions: 1) All pericyclic reactions are single step mechanism. 2) All pericyclic reactions have conjugated cyclic transition state. 3) All pericyclic reactions are internally self-sufficient mean (no extra reagent and catalyst is required) they initiated by thermally or photo chemically. 4) All pericyclic reactions are stereospecific in nature mean (specific stereoisomer in reactants form specific stereoisomer in products). 5) All pericyclic reactions show equilibrium state mean (reactants and products have ability to inter change with each other). Types of pericyclic reactions: There are following types of pericyclic reactions 1) Electrocyclic reactions 2) Cycloaddition reactions 3) Sigmatropic rearrangement 1) Electrocyclic Reactions “An electrocyclic reaction is a reversible reaction that can involve ring closure or ring opening of one molecule of reactant to form one molecule of product.” Type of Electrocyclic Reactions: i) Electrocyclic ring closure reactions: “An electrocyclic ring closure is an intramolecular reaction that forms a cyclic product containing one more σ bond and one fewer π bond than the reactants.” ii) Electrocyclic ring opening reactions: “An electrocyclic ring opening is a reaction in which an σ bond of a cyclic reactant is cleaved to form a conjugated product with one more π bond.” To draw the product in each reaction, use curved arrows and begin at a π bond. Move the π electrons to an adjacent carbon-carbon bond and continue in a cyclic fashion.

Hi! I am Tutor Francis, Mathematics tutor, I have a degree in Computer Science, honors First Class. I have 5 months of experience teaching online classes to secondary and high school students. My class is focused on GCSE students beginning from Key Stage 1 to Key Stage 3. I also teach primary students. If you need to revise or learn the following Math topics then I can help you easily understand them; 1. 3D Shapes. 2. Algebra. 3. Angles. 4. Circles (PIE). 5. Gradient. 6. Indices. 7. Inequalities. 8. Money Problems. 9. Multiples and Factors. 10. Percentage Change. 11. Probability. 12. Proportions. 13. Ratio. 14. Reverse Percentages. 15. Sequences. 16. Speed, Distance, and Time. 17. Standard Form. 18. Translation etc. More will be added with time. My Class Format is below; Introductions. Current class level. Areas of difficulty per subject. Areas of strength. Exercises. After class discussion Take-home assignment. Goodbye, greetings. End of Class. Most of my classes will require the student to highlight areas of focus and difficulty so we can work on them with examples. The reason for this is to increase confidence levels in other subjects as well. Students tend to do better in other classes if they are mentally strengthened by overcoming challenges. I look forward to tutoring you and increasing your understanding of different Math topics. Hopefully, I see you in class. If you need help understanding specific Mathematics topics in preparation for GCSE then I am your tutor.

Matematica

Hello, I am a mathematics teacher. I am from Jordan and live in Germany. Mathematics is my passion and so is also my teaching full of patience and understanding to my students. But to reach the goal of course needs to work hard sometimes and stay on track. I have worked as a teacher for several years in a middle school, in a high school and at a university. I taught math topics for all middle and high school grades as well as Calculus 1, 2, 3 at the university. Studying at universities in different countries has helped me keep up with the latest international research as well. I will be happy to share my knowledge with you as my students to help you reach the best level of mathematics you need and to wake up the fire of mathematics in you as much as possible. Please feel free to contact me for a good and successful learning time in any subject of mathematics. To learn about my qualities, simply book a trial math lesson with me. see you soon...
