Describe the Kekule and delocalised model of benzene and explain some of the reasons why the kekule is disproved

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 hydrogen atomsEach carbon atom bonded to 2 others and a hydrogenSpare, delocalised electon located in p-orbital, can overlap sideways to form pi bond.
Reasons - 1 = Unreactive, 2 = Carbon-carbon bond lengths, 3 = Enthalpy of hydrogenation

Can you help me with the question: "State and explain the trend in boiling temperature of hydrogen halides down the group"?


State the relative charge and relative mass of a proton, of a neutron and of an electron. In terms of particles, explain the relationship between two isotopes of the same element. Explain why these isotopes have identical chemical properties.


Explain: 1. Why butanoic acid has a higher boiling point than butan1-ol? 2. Why carboxylic acids of short chain length are more soluble in water than those with longer carbon chain length?


Why does magnesium have a higher melting point than sodium?
