An isotope is a different form of the same element. They differ from each other by the number of neutrons, however they have the same number of protons and electrons. This results in a different atomic...

It's really useful to know that 'phile' means love.

Electrophiles 'love' negative charge - this means they are attracted to regions of negative charge. And as such they tend to be positiv...

Bond lengths - a single bond is 0.153nm while a double bond is 0.134nm, making Kekulé's model of alternating single and double bonds asymmetric. Other evidence shows benzene to be symmetr...

As the charge of an ion increases, so does its charge density. The ion can therefore form stronger electrostatic forces of attraction, resulting in stronger bonds. As these bonds form to produce a lattice...

An aldehyde will react with Tollen's reagent to form a characteristic silver mirror, whereas a ketone will not react. This is because an aldehyde can be oxidised to a carboxylic acid, reducing Tollen's re...
