Difference between Ziegler natta catalyst and single site catalyst​...????

Answer:

A Ziegler–Natta catalyst, named after Karl Ziegler and Giulio Natta, is a catalyst used in the synthesis of polymers of 1-alkenes (alpha-olefins). ... This class of catalyst dominates the industry. Homogeneous catalysts usually based on complexes of Ti, Zr or Hf.

The usual definition of single - site molecular catalyst is a catalyst which contains a single metal center. The metal atom usually has an open - side, or an easily replace- able group, where it binds substrates and where bonds are broken and formed.
