minutes. I want a brief answer without a complete solution

Which of the following absorption maxima is not in the visible range of the electronic spectrum? Select one: O max = 830 nm Amax = 430 nm o Amax = 670 nm Amax = 530 nm The reactions of [PtCl 12- with PR3 followed by NH3 (reaction I) and of (PtCl.]2+ with NH3 (reaction II) are ways of preparing Select one: O I: trans-[PtCl2(NH3)(PR3)] II: trans (PtCl (NH3)2] OI: trans-(PtCl (NH3) (PR3). II cis (PtCl2(NH3)2] OI: cis (PtCl (NH3)(PR3)] II cis-[PCL,(NH3)2] OI: cis-[PtCl2(NH3)(PR) II trans (PtCl (NH3)2]
