Transition metal ions have partially filled d sub-shells. These shells split into two levels and the electrons in the lower levels can be excited to the higher ones by absorbing an amount of energy equiva...

Fisrt you would use the chemical shift data of the main peaks, this gives you an idea of the chemical environment of the hydrogen atom that caused this peak. A more downfield signal (higher chemical shift...

In chemistry there are two distinct theories to explain acid-base reactions; the Bronsted-Lowry and Lewis acid-base theories. The Bronsted-Lowry theory talks about removal or transfer of ...

This is a long answer (6 mark) question, which means you need to demonstrate your written communication of scientific ideas.

The first thing I would do in a question is identify the key words.

I don't think i've ever taught an A-level chemistry student that hasn't said this at some point. Because it is the part of chemsitry (in my opinion) that seems the most daunting. I generally wait until to...
