Vedclass · Answer

(C) According to Fajan's rule,covalent character increases when the cation is smaller and has a higher positive charge,and the anion is larger and has a higher negative charge.$(i)$ $I^-$ has a larger size than $F^-$,so $KI$ has more covalent character than $KF$. Thus,$KF $(ii)$ $Li^+$ is smaller than $K^+$,so $LiF$ has more covalent character than $KF$. Thus,$LiF > KF$,making $LiF $(iii)$ $Sn^{4+}$ has a higher positive charge than $Sn^{2+}$,so $SnCl_4$ has more covalent character than $SnCl_2$. Thus,$SnCl_2 $(iv)$ $Cu^+$ has a pseudo-noble gas configuration $(d^{10})$,which causes higher polarization than the noble gas configuration of $Na^+$. Thus,$CuCl > NaCl$,making $NaCl Therefore,the correct orders are $(i), (iii),$ and $(iv)$.

Which of the following orders are correct regarding their covalent character?
$i. KF < KI$
$ii. LiF < KF$
$iii. SnCl_2 < SnCl_4$
$iv. NaCl < CuCl$
The correct option is
