We can take the electrophilic addition of bromine to ethene as an example. The double bond in ethene acts as an area of high electron density causing an induced dipole on the Br₂ molecule, givi...

For the boiling point to be reached all of the intermolecular bonds must be broken. In an alkane the only two elements are hydrogen and carbon. The molecular structure of the alkane means that the intermo...

Alkanes are non-polar so only have London forces between them. These intermolecular bonds are weak, and easily overcome with little energy. This means that alkanes have a low boiling point hence they are ...

With ionic bonding, two ions of the opposite charge are attracted to each other to form the bond. With ionic bonding, it is the strong electrostatic force of attraction between ions. While, covalent bondi...

For the technique of chromatography, there are two 'phases', the stationary phase and the mobile phase. In paper chromatography, the stationary phase is the paper and the mobile phase is...
