The enthalpy Change of Hydration for cyclohexene is 120 kJmol^-1 therefore if the Kekule model is correct then the Enthalpy change of Hydration would be 360 kJmol^-1 however as it is c...

Both molecules have a C-Br bond, which will be polar due to their difference in electronegativities (bromine is more electronegative than carbon). In CBr3CBr3 the dipoles cancel so the overall molecule is...

In dynamic equilibrium the rate of the foward reaction is equal to the rate of backward reaction. Also the concentration of the products and reactants stay constant.

(labelled diagrams of both benzene and phenol would be used to show the overlapping p orbitals above and below the plane of the molecule, with phenol showing the partial delocalisation of the oxygen lone ...

The oxidation number of an ion is the same as its charge. We know that the oxidation number of K+ is +1 and the oxidation number of O2- is -2, but we don't know the oxidation number of Mn so let's call th...
