Kekulé's model of benzene is that it has 3 double bonds, in a ring of 6 carbons.One - Benzene isn't very reactive, so if Kekulé's model were to be correct, there would be 3 double bonds in benzene, ...
First, we have to convert the starting measurements for the HCl and CaCO3 content into moles so we can compare the ratios to the formula. 40cm^3=0.04dm^30.04dm^32.5mol.dm^-3=0.1 moles of HClmass/molar...
Endothermic reactions take in heat from the surroundings, whereas exothermic reactions release heat to the surroundings. Exothermic reactions release heat as the energy released from the bonds being made ...
The p orbitals on each carbon atom in benzene overlapThere is delocalisation of electrons in the ring (not 3 localised C==C double bonds)This makes benzene more thermodynamically stable than predictedIt t...
