A) 2.6
B) 1.71
C) 1.4
D) 0.95
Correct Answer: B
Solution :
\[{{C}^{4-}},{{N}^{3-}}\]and\[{{O}^{2-}}\]are isoelectronic species. The size of ionic radius of isoelectronic species decrease with increase the nuclear charge. Hence, the order of ionic radius is: Species: \[{{C}^{4-}}~\,\,\,\,\,\,>\,\,\,\,\,\,~{{N}^{3-}}\,\,\,\,\,\,~>\,\,\,\,\,\,\,~{{O}^{2-}}\] lonic radii \[2.60~~~~~~~~1.71~~~~~~~~~~~1.40\]You need to login to perform this action.
