Can we predict the trend in reactivity of fluoromethane, chloromethane, bromomethane and iodomethane based on the information above? the C-F
The mechanism for this reaction is nucleophilic substitution Hydroxide ions act as nucleophiles (a species with a negative charge or

Questions based on carrying out titration and interpreting the results are common both at AS and A level. Before we

So now you are confident with run-of-the-mill, text book titration questions it’s time to tackle the types of question you
You may have come across titration calculations at GCSE, and this post builds on that knowledge. The good news is
It is assumed that you covered the basics of concentration at GCSE. Essentially, you need to be able to work
If you come unstuck working through the questions, leave a comment and I’ll get back to you. Good luck 😊!
We can use the ideal gas equation to find the molar mass (relative molecular mass) of a volatile liquid. In
The ideal gas equation is an amalgamation of Boyle’s law, Charles’s law and Avogadro’s law and it describes the behaviour
This leads on directly from the previous position molar volume . The video works through a problem to find the
