1.	Different steps involved ind the mechanism of preparation of sodium hydoxide by Castner process are given bleow .Arrange them in correct sequence . (i)2Cl^(-)rarr Cl_2+2e^(-) ( b) Na_a Hg-2e^(-)rarr2Na^++Hg ( c) 2H_2O+2e^(-) rarr H_2+2OH (d ) Hg+2Na^+2bare rarr Na_2HG ( e)2NaClrarr2Na^+2Cl ( f) 2Na^(+)+2OH^(-)rarr2NaOH
