STD 11 - 8.2 Organic chemistry isomerism — JEE STD 11 Science — Question

$Sn ^{2+}+2 e ^{-} \rightarrow Sn$

$Sn ^{4+}+4 e ^{-} \rightarrow Sn$

The electrode potentials are; $E _{ Sn ^{2+} / Sn }^{\circ}=-0.140\, V$ and $E _{ Sn ^{4+} / Sn }^{\circ}=0.010\, V$. The magnitude of standard electrode potential for $Sn ^{4+} / Sn ^{2+}$ i.e. $E _{ Sn ^{4+} / Sn ^{2+}}^{\circ}$ is $.....\times 10^{-2}\, V$. (Nearest integer)

$A.$ $KF > KI ; LiF > KF$

$B.$ $KF < KI ; LiF > KF$

$C.$ $SnCl _4 > SnCl _2 ; CuCl > NaCl$

$D.$ $LiF > KF ; \quad CuCl < NaCl$

$E.$ $KF < KI ; CuCl > NaCl$

Where $A$ is $PCl^+_4$ while $B$ is $PCl^-_ 6$

Which of the following statement is INCORRECT :

$(I)$ $B$ to $A$ involvement of number of $d-$orbital in hybridization increases

$(II)$ $A$ to $B$ precentage of $p-$character in $P-Cl$ bond increases

$(III) $ Number of covalent bond in $A$ and $B$ are same

$(IV)$ $B$ is product of Lewis acid-base interaction which is associated with super octet molecule only
