The boiling points of ammonia (NH3), fluorine (F2) and bromine (Br2) are -33, -188 and +59 degrees celsius respectively. Explain the differences in these boiling points, including the names of any relevant forces and particles.

Differences in boiling points between molecules are due to varying strength of intermolecular forces. From the data given, we know Br₂ must have the strongest intermolecular forces as it has th...

Explain and draw the mechanism of the nucleophillic substitution reaction between bromoethane and aqueous sodium hydroxide. How is this reaction different to the elimination reaction which may occur?

The d+ carbon on the bromoethane is susceptible to attack by the OH- nucleophile (negative ion with a lone pair)( the lone pair is very important as this carries out the attack!!!).

When the nucleo...
