About me

Hi there, I'm Liam! I recently graduated from Manchester with a 2:1 in Biochemistry, and am about to begin my teacher training course in Chemistry!

I achieved 6A* and 5A grades at GCSE, and 40/45 points on the IB Diploma during sixth form (including 7/7 chemistry and 6/7 biology). 

I am a very sporty person, and have coached cricket and football to young people for a number of years. I try to create a friendly, comfortable atmosphere between me and the student, in which we can work together to achieve you the best grade possible! I would also like to help with university applications, personal statements, and any other issues you would like to talk about.

Thank you for reading, and hopefully speak to you soon!

Questions Liam has answered

What is hybridisation?

Hybridisation is a chemical phenomenon that occurs in certain atoms, whereby atomic orbitals 'mix' or 'hybridise' from their usual arrangement to form a more energetically-favourable orbital arrangement. Consider the molecule Methane (CH4); in this molecule, the central carbon atom forms equivalent covalent bonds with 4 hydrogen atoms. However, the outer energy level of carbon shows that there are two electrons contained in the 2S orbital, and two electrons contained in the 2P orbital. These P orbitals are of higher energy than the S orbitals, so carbons orbital arrangement must change in order to form the 4 equivalent covalent bonds. This is where hybridisation comes in: an electron is promoted from the 2S orbital into the unoccupied 2Pz orbital, and then hybridisation of the second energy level occurs. This means that the 2S orbital now containing only one electron mixes with the three 2P orbitals, each containing one electron, to form 4 new "SP3" hybrid orbitals. These  orbitals are all of equal energy, which is slightly lower than that of the 2P orbitals, which means that it is energetically favourable for carbon to hybridise in methane. This explains how it can form 4 equivalent covalent bonds in methane! (An energy level diagram of the orbitals would also be useful to explain, but I a, not sure how to draw one here).
