Consider the following statements :
(1)Brideherated halides are inert towards both `S_(N^(1)) and S_(N^(2))` reaction till one of the ring size is eoght member ring )
(2) The first step in both `S_(N^(1))` and `E_(1)` reactions is the same
(3) `S_(N^(2))` reactions proceed with total retention of configuration
(4) `E_(2)` elimination s are by the use of a solvent of low polarity and high concentration of a stromng base
Which of the above statements are correct?
