Explain why phenol is nitrated more readily than benzene.

Phenol has a lone pair of electrons on the O group which can be delocalised into the benzene Pi system2) This delocalisation increases the electron density in the pi system compared to benzene3) Thi...

Explain why water molecules form on average two hydrogen bonds per molecule, whereas ammonia molecules (NH3) form only one.

A hydrogen bond requires both a lone pair of electrons on a O, N or F atom and a hydrogen atom. In water there are two lone pairs and two hydrogen atoms, allowing the formation of two hydrogen bonds. In a...

Why does grinding a solid reactant down into smaller lumps increase the rate of a reaction? (2/3 marks)

As grinding down the solid increases the exposure of particles on the surface, this increases the frequency of reactant particle collisions which then increases the rate of reaction.
