All of the above

Vedclass · Answer

(D) The stability of high oxidation states in $d$-block and $p$-block elements generally decreases down a group due to the inert pair effect and the decrease in the strength of the metal-oxygen bond.$1$. For the oxoanions of $3d$ transition metals,$CrO_4^{2-}$ (Cr is $+6$) is more stable than $MnO_4^{2-}$ (Mn is $+6$) and $FeO_4^{2-}$ (Fe is $+6$).$2$. Comparing $CrO_4^{2-}$ and $WO_4^{2-}$,the stability of the $+6$ oxidation state increases down the group $(Cr $3$. For group $16$ elements,the stability of the $+6$ oxidation state decreases down the group $(Se > Te > Po)$ due to the inert pair effect.Thus,all the given orders are correct.

Property	Metal
$a$. Element with highest second ionization enthalpy $(\Delta_{i} H_2)$	$i$. $Co$
$b$. Element with highest third ionization enthalpy $(\Delta_{i} H_3)$	$ii$. $Cr$
$c$. $M$ in $[M(CO)_6]$	$iii$. $Cu$
$d$. Element with highest heat of atomization $(\Delta_{a} H)$	$iv$. $Zn$
	$v$. $Ni$

Which of the following represents the correct order of stability for the given oxidation states?
