Hello! My name is Conor, and I'm a second year Biochemistry student at the University of York, with a fascination for all things to do with science! I hope that during our sessions I can not only impart on you my knowledge and understanding, but also spark a passion for the study of the fundamental processes which govern the complex universe we live in!
Throughout all the sciences two key themes are always present: key concepts and understanding them. In science it is vital that students understand key concepts such as osmosis, partially-permeable membranes, integration and so on! Without this foundation it is difficult for students to thrive in a classroom environment and perform well in exams, which will test understanding of these concepts. My sessions therefore focus on teaching tutees a working knowledge of whatever key concepts they are struggling to grasp fully in the classroom and then use past paper questions to check everyone has understood what I've just taught them! Didn't quite get it first time? That's ok! I'm a patient, approachable and friendly guy who will work with you until you can explain that tricky topic you were struggling with just a few minutes ago to anyone, even Mr Examiner!
Although I have a basic teaching template, my sessions will work around you. If you have a preferred style of learning I am flexible enough to adjust my sessions based on how you work best.
If you feel that I can help you in any way, feel free to book a free "Meet The Tutor" session or contact me via my WebMail. Please make sure to state what subject you're struggling with, the specific topic within that subject you would like help with and the exam board.
Thank you for reading my résumé and I look forward to meeting you!

*First draw out each compounds' structural formula (an image of the "shape and arrangement of the atoms in space"), then identify all functional groups in each compound.
*Add Tollens' reagent to all three, the compound which provides a silver mirror / precipitate, is compound B. This is because B is the only one to have an aldehyde group, which is oxidised by Tollens and gives a positive result. Ketones are NOT oxidised by Tollens and so give a negative result (no mirror).
*Next, add acidified potassium dichromate, formula Cr2O72-, to all three. A and B give a positive result for this test, a colour change from orange to green, as they both have either primary or secondary alcohols. C gives a negative result, no colour change, as it has a tertiary alcohol which won't be oxidised by the dichromate.
Tollens = X, Cr2O7 = ✓ -> Compound A
Tollens = ✓ -> Compound B
Tollens = X, Cr2O7 = X -> Compound Csee more
