Kekule structure advantages: Useful for mechanistic understanding, can push arrows to advise likely regiochemistry. Disadvantages: ignores aromatic stablisation, drawn structure much higher energy than ac...

The more polarising ion is the one that can distort the electron cloud of the other ion in the ionic bond more. The top of group two are the most ionising, since these have a small electron cloud and a bi...

GCSE answer: Butane is a larger molecule than ethane meaning that the intermolecular forces between its molecules are stronger. In order for a compound to boil these intermolecular forces need to be overc...

No atoms are lost or made during a chemical reaction, so the total mass of the products is equal to the total mass of the reactants.

Kekule Model - 6 membered carbon ringComposed of carbon atoms joined together by alternating single and double bonds
Delocalised Model - A planr cyclic hydrocarbon composed of 6 carbon atoms and 6 hy...
