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...

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...

At room temperature and pressure, the first 4 alkanes are all gases, but the first 4 alcohols are all liquids. Explain this.

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 ...

What is the difference between ionic and covalent bonding?

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...
