The chlorine atom is smaller than the iodine atom therefore its 7 outer electrons are closer to the nucleus than the 7 outer electrons in iodine. In turn, this means the positively charged chlorine nucleu...

Each carbon atom forms covalent bonds with three other carbon atoms and one electron from each carbon atom is delocalised.It is these delocalised electrons which allow electricity to be conducted as they ...

As you go along a period, there is an increasing number of protons in the nucleus of each atom meaning that the nucleus has an increasing positive charge.This means that the electrons are puller closer to...

Increasing the pressure shifts equilibrium towards the side with fewer moles of gas, so in this reaction the equilibrium will move to the right. Hence, a shift towards the right hand side...

1. 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...
