Compare non transition and transition elements on the basis of their.
  1. Variability of oxidation states.
  2. Stability of oxidation states.

Answer

  1. Oxidation states of transition elements differ from each other by unity. In non-transition elements oxidation states normally differ by a unit of two.
  2. In transition elements higher oxidation states are favoured by heavier elements whereas in non-transition elements lower oxidation state is favoured by heavier elements.

CCl4 and water are immiscible whereas ethanol and water are miscible in all proportions. Correlate this behaviour with molecular structure of these compounds.CCl4 is a non-polar covalent compound, whereas water is a polar compound. CCl4 can neither form hydrogen bonds with water molecules nor can it break hydrogen bonds between water molecule, therefore, it is insoluble in water. Ethanol is a polar compound and can form hydrogen bonds with water, which is a polar solvent, therefore it is miscible with water in all proportions.
