Explain why ionic compounds such as potassium sulfide have high boiling points and conduct electricity when dissolved in water?

Such compounds have high boiling points because bonds between the atoms are strong. The boiling point largely depends on electronegativity difference between the atoms - as this difference is greater, so ...

Explain how the differences in structure between Diamond and Graphite give rise to their different properties

Carbon has 4 electrons in its outer shell, so to fill its outer shell (which can hold up to 8 electrons) and be stable, it wants another 4 electrons. It can do this by sharing its 4 electrons in 4 strong ...

How does increasing the temperature affect the yield of products of a reaction at equilibrium, where the forward reaction is exothermic?

The position of equilibrium changes after the temperature increases according to Le Chatelier's principle, which states that if a change is applied to a system in equilibrium, then the position of equilib...

Draw a mechanism for electrophilic addition?

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...

Explain why longer chain alkanes have a higher boiling point than shorter chains.

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...
