Benzene is stable due to its delocalised ring of electrons - which forms as a result of the carbon-carbon bonds being neither single nor double bonds, instead an intermediate length with electrons in the ...

So firstly, we need to work out the basic shape of the molecule which we can do by drawing the lewis structure (dot and cross diagram) and counting the number of charge clouds around the central atom. In ...

Benzene has a delocalised pi system in which p orbitals of all carbon atoms overlap above and below the carbon ring. Alkenes, however, have localised pi-orbital overlaps between two carbon atoms. The elec...

This is a nice simple calculation question which explores some basic thermodynamic principles and begins to apply them to simple reactions (in this case, solid salt dissolving in water) allowing predictio...

React a sample of each compound with Tollens reagent. The aldehyde (propanal) will be oxidised to a carboxylic acid (propanooic acid) and will form a silver mirror. No change will be observed with the ket...
