    If wavelength of 1st line of Balmer series, is \[Fe(II)\], then wavelength of 2nd line of Balmer series is

    A)  \[Mn(II)\]                          

    B)  \[Cr(II)\]

    C)  \[\sigma \]                        

    D)  \[{{C}_{2}}{{H}_{5}}OH+HX\xrightarrow{Zn{{X}_{2}}}{{C}_{2}}{{H}_{5}}X,\]

    Correct Answer: A

    Solution :

                    For 1st line of Balmer series, \[O\to C\] \[O\to B\] For 2nd line of Balmer series, \[O\to A\] and \[A{{g}_{2}}O+{{H}_{2}}O+2{{e}^{-}}\xrightarrow{{}}2Ag+2O{{H}^{-}}\] \[Fe(III)\] \[Fe(II)\] \[Mn(II)\]
