An isomer of the complex CoBrCl2(en)2(H2O), on reaction with concentrated H2SO4 (dehydrating agent), suffers no loss in weight and on reaction with AgNO3 solution it gives only white precipitate, which is soluble in NH3 solution.
The incorrect statement about complex is :
(1) It can show geometrical isomerism
(2) cis isomer is optically active
(3) Trans isomer is optically active
(4) It can exhibit solvate isomerism
