Draw the shape of an SF6 and SF4 molecule, indicating bond angles and any lone pairs which may influence these. What shape is the SF6 molecule?

Sulfur is a group six element, meaning it can form up to six bonds with halogen atoms such as F or Cl. In the instance where only four valence electrons of S are bonded to the halogens, the remaining two ...

Why is there a difference in mechanism between tertiary halogenoalkanes and primary halogenoalkanes in nucleophilic substitution?

The difference in mechanism between tertiary halogenoalkanes and primary halogenoalkanes is caused by the difference in relative stability between the two carbocation intermediates formed. In the case of ...

Explain why the enthalpy of lattice dissociation of potassium oxide is less endothermic than that of sodium oxide.

Lattice dissociation enthalpy is the enthalpy change when one mole of a gaseous ionic lattice dissociates into isolated gaseous ions. The process is endothermic because energy is required to overcome the ...
