Vedclass · Answer

(B) From the periodic table segment:$D$ is $B$ $(Z=5)$,$H$ is $C$ $(Z=6)$$E$ is $Al$ $(Z=13)$,$G$ is $Si$ $(Z=14)$$A$ is $Zn$ $(Z=30)$,$F$ is $Ga$ $(Z=31)$$C$ is $Cd$ ($Z=48$ is given,so $C$ is $Hg$,$Z=80$)Analysis of statements:$A$ $(ZnO)$ and $E$ $(Al_2O_3)$ are indeed amphoteric. (Correct)$Z_{eff}$ for $Al$ $(Z=13)$ is $3.5$ and for $Ga$ $(Z=31)$ is $4.5$ (using Slater's rule),difference is $1.0$,not $1.5$. (Incorrect)$G$ $(SiO_2)$ and $H$ $(CO_2)$ are acidic in higher oxidation states. (Correct)$H$ $(C)$ forms $CO$ (neutral oxide) by dehydration of $HCOOH$ with conc. $H_2SO_4$. (Correct)Thus,the incorrect statement is $B$.

List-$A$	List-$B$
$(1)$ $He$	$(A)$ High electron gain enthalpy
$(2)$ $Cl$	$(B)$ Electropositive element
$(3)$ $Ca$	$(C)$ Strong reducing agent
$(4)$ $Li$	$(D)$ High ionization enthalpy

Column-$I$	Column-$II$
$A$. Ionisation potential	$P$. $O < F < N$
$B$. Electronegativity	$Q$. $N < O < F$
$C$. $Z_{eff}$	$R$. $O < N < F$
$D$. Electron affinity	$S$. $N < C < O$

Based on the provided periodic table segment,identify the incorrect statement.
