Differences between microsporogenesis and megasporogenesis . Which type of cell division occurs during this events? Name the structures formed at the end of this two events.

When bromo benzene is monochlorinated, two Isomeric compounds A and B are obtained. Monobromination of A gives several isomeric products of molecular formula C_6 H_3 CI Br_2 , while monobromination of B yields only 2 isomers C and D . Compound C is identical with one of the compounds obtained from bromination of A , however D is totally different from any of the isomeric cómpounds obtained from the bromination of A , Give structures of A, B, C and D and also structures of four isomeric monobrominated products of A Support your answer with reasoning.
