About me

About me:

I am a third year Chemistry student with a passion and curiosity for many branches of science, most strongly for Chemistry. This passion and curiosity I hope to bring to my tutees.

Experience:

I've been tutoring Chemistry on MyTutorWeb for over a year now, meaning I've taught both AS and A2 on AQA, OCR and Edexcel numerous times. From this I understand the need for clear communication and direction in sessions, as well as making it fun! 

Our sessions:

The content and approach to sessions can be wholly dictated by you, whether you want help with understanding a single topic/subject or with approaching and answering exams in the right way. 

Ultimately, I hope to make sessions enjoyable as well as helpful. In my view, learning (especially science) should be fun and engaging; I hope to make this the case for you!

What is chirality/optical isomerism?

Chirality (or optical isomerism) is a physical property of a molecule which has a non-superimposable mirror image. In other words, a molecule which, when reflected cannot be rotated in any way to make the original molecule. 

The simplest example of this is human hands, they are mirror images but cannot be superimposed upon one another. Another example is the letter R. You can prove this to yourself by looking at your hands side by side with both palms facing towards you and try to superimpose them. You'll soon see that no matter how much you rotate them, they will not fit on top of one another.

The most common optical isomers are 'asymmetric' carbons, those with 4 different groups bonded to them (e.g. (NH2)HC(OH)(COOH) ), however it can be found in coordination complexes and even larger organic molecules. Optical isomers are indistinguishable in their chemical properties as they take part in the same reactions with achiral reagents, however if polarised light is passed through a solution of a chiral molecule, it will be rotated slightly. Passing polarised light through this molecule's optical isomer will rotate the light the same amount in the opposite direction.

Another key difference of two optical isomers is how they interact with biological systems, most notably enzymes (which are themselves chiral). Often, only one optical isomer will take part in reactions catalysed by enzymes and the other will not react at all (due to the importance of shape in enzyme active sites). A perfect example of this is the molecule carvone, one isomer of which smells like spearmint and the other of caraway seeds. The difference in smell is due to the different interaction with receptors in the nose.
