A) \[{{P}_{2}}{{O}_{5}}\]
B) \[Mn{{O}_{2}}\]
C) \[M{{n}_{2}}{{O}_{7}}\]
D) \[{{P}_{2}}{{O}_{3}}\]
Correct Answer: D
Solution :
According to Fajan's rule compounds having large charge on cation are more covalent or least electrovalent. So, compounds having low charge on cation will be more electrovalent or ionic. \[\begin{matrix} \overset{+4}{\mathop{Mn{{O}_{2}}}}\, & \overset{+7}{\mathop{M{{n}_{2}}{{O}_{7}}}}\, \\ \overset{+5}{\mathop{{{P}_{2}}{{O}_{5}}}}\, & \overset{+3}{\mathop{{{P}_{2}}{{O}_{3}}}}\, \\ \end{matrix}\] So, \[{{P}_{2}}{{O}_{3}}\] will be most ionic.You need to login to perform this action.
