The oxygen on the OH (of the phenol) has a lone pair which it donates into the delocalised pi system of the ringThis activates the ring and there is now a high electron density.This is now strong enough t...

1.Butanoic acid has stronger intermolecular forces (hydrogen bonding) because it has two highly electronegative oxygen atoms in its structure, whereas butan-1-ol has only one. Therefore t...

Silicon has a Chrystal structure with many covalent bonds between atoms. Covalent bonds are strong and need a large amount of energy to be broken in order to melt Silicon.

Hydrogen bonding is an intermolecular interaction between a partially positively charged hydrogen atom on one molecule and a partially negatively charged atom on another molecule. The difference in charge...

First acidify the solution using dilute nitric acid, then add silver nitrate. The silver ions should react with the halide ions to form a precipitate, with colour depending on which halide ion is...
