Redox Reactions And Electrochemistry Ques 744
Question: The largest oxidation number exhibited by an element depends on its outer electronic configuration. With which of the following outer electronic configurations the element will exhibit largest oxidation number-
Options:
A) $ 3d^{1}4s^{2} $
B) $ 3d^{3}4s^{2} $
C) $ 3d^{3}4s^{1} $
D) $ 3d^{5}4s^{2} $
Show Answer
Answer:
Correct Answer: D
Solution:
[d] Maximum oxidation state ford-block elements $ ~=(n-1) $ unpaired $ d{{e}^{-}}+ns{{e}^{-}} $ For $ 3d^{5},4s^{2} $ configuration Maximum oxidation number $ =5+2=7 $
