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 \[A{{g}_{2}}O+{{H}_{2}}O+2{{e}^{-}}\xrightarrow{{}}2Ag+2O{{H}^{-}}\] \[Fe(III)\] \[Fe(II)\] \[Mn(II)\]You need to login to perform this action.
