Everything you need to know about C-13 NMR spectroscopy
13C NMR signals are considerably weaker than 1H NMR signals because the natural abundance of 13C is 1.1%. We also

Everything you need to know about proton (H-1) NMR Spectroscopy
In proton or 1H NMR spectroscopy the sample is dissolved in a solvent such as tetrachloromethane, CCl4, or trichlorodeuteriomethane, CDCl3

Understanding nuclear magnetic resonance spectroscopy
We are familiar with the idea that electrons possess an intrinsic quantum property known as spin (we met this when

Elimination reactions – dehydrating an alcohol
If we dehydrate an alcohol, we are essentially removing a water molecule and the product will be an alkene. The

Electrophilic addition in alkenes (3) – reaction with water to form an alcohol
The reaction of an alkene with water to from an alcohol is an example of a hydration reaction. The alkene

Electrophilic addition in alkenes (2) – the bromine water test
The classic test for an alkene is to shake your sample with orange bromine water, and if the molecule contains

Making addition polymers by radical polymerisation
The mechanism for addition polymerisation is another example of a radical reaction. Teflon (PTFE), famously known for its non-stick properties,

Addition polymers and their properties
Polymers are long chain molecules made via addition polymerisation or condensation polymerisation – the result are all the plastics, fibres
Electrophilic addition reactions in alkenes (1)
Now that you have been introduced to the terminology and fundamental ideas of reaction mechanisms, it is time to focus

Stabilising carbocations through inductive and mesomeric effects
Inductive and mesomeric effects both play an important role in determining how organic reactions happen through their abilities to stabilise
