Salve
sono una docente universitaria di Chimica ed oltre alla mia professione ho esperienza di divulgazione della Chimica a vari livelli. Se la Chimica proprio non ti piace, se fai fatica a capirla se sei convinto che richieda tanta, troppa, memoria...allora probabilmente ti stupirá scoprire che la Chimica puó essere molto piú semplice di quello che credevi.
Offro lezioni di Chimica Generale, Inorganica ed Organica per qualunque livello di studio: dalla scuola superiore all`Universitá.

Hi! I'm Rose, a committed and passionate tutor. I earned my Master's Degree in Chemistry and have dedicated the past 18 years to teaching my favorite subject, Chemistry. Holding full international certification and qualification as a lecturer and teacher in Chemistry I specialise and bring valuable experience with AP, IB, A-Level, GCSE/IGCSE and College Chemistry. I take great joy in imparting my enthusiasm for Chemistry to all my students.
I have provided online tutoring for over 600 students, primarily from the US and UK, and a few from countries such as Italy, Germany, Singapore, Japan, UAE, and India. Over the past 18 years, I have completed more than 20,000 successful tutoring hours (and still counting).
As an academic coach, I am versatile in my approach. Most students are visual learners, and recognizing this, I utilize molecular models accessible via webcam to elucidate chemical concepts such as molecular reactions, balancing, molecular shapes, and reaction mechanisms. Additionally, I employ screen sharing to present animation videos, and simulations when applicable, facilitating quicker and enhanced comprehension and retention of these concepts.
With an extensive knowledge base in the subject I tutor (having been consistently among the top in my class in both High School and University), I ensure that lessons are interactive rather than one-way. Throughout the tutoring sessions, I engage students with related questions and frequent quizzes to gauge their understanding and identify any topics that may require revisiting. I actively encourage students to ask questions, fostering a dynamic and participative learning environment.
Patience is a key attribute of mine, and I personalize the curriculum to cater to the individual needs of each student. As a friendly and patient teacher, I encourage students to unleash their maximum potential one step at a time. Collaborating with me is sure to be a pleasant and rewarding experience.

Hey, I'm Ayesha. I've specialized in mathematics from GCUF. I am a passionate tutor in Mathematics. I have taught students up to high school. I can teach from basic level mathematics to Group Theory, Set Theory, Basic Calculus, Multivariable Calculus, Linear Algebra, Vector Algebra, and Oxford Syllabus. I have 4+ years of teaching experience at local tuition centers. I am currently tutoring on Course Hero.
I'll provide you lecture notes, pdf documents, and visualization of the lecture on the virtual whiteboard as I'll be satisfied only if MY STUDENTs are satisfied.
You can book a trial lesson now to assess my skills and abilities. Just leave a message and I'll catch you at the exact moment.

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.
