[JEE 2000]
Ans. (C)
Q. The correct order of radii is:
$(\mathrm{A}) \mathrm{N}<\mathrm{Be}<\mathrm{B}$
(B) $\mathrm{F}^{-}<\mathrm{O}^{2-}<\mathrm{N}^{3-}$
(C) $\mathrm{Na}<\mathrm{Li}<\mathrm{K}$
$(\mathrm{D}) \mathrm{Fe}^{3+}<\mathrm{Fe}^{2+}<\mathrm{Fe}^{4+}$
[JEE 2000]
Ans. (B)
Q. The $\mathrm{IE}_{1}$ of Be is greater than that of B.
[JEE 2001]
Ans. True
Q. The set representing correct order of $\mathrm{IP}_{1}$ is
(A) K > Na > Li
(B) Be > Mg > Ca
(C) B > C > N
(D) Fe > Si > C
[JEE 2001]
Ans. (B)
Q. Identify the least stable ion amongst the following:
(A) $\mathrm{Li}^{-}$
(B) $\mathrm{Be}^{-}$
(C) $\mathrm{B}^{-}$
(D) $\mathrm{C}^{-}$
[JEE 2016]
Ans. (B)
Q. The increasing order of atomic radii of the following Group 13 elements is
(A) Al < Ga < In < Tl
(B) Ga < Al < In < Tl
(C) Al < In < Ga < Tl
(D) Al < Ga < Tl < In
[JEE 2016]
Ans. (B)
Increasing order of atomic radii: Ga < Al < In < Tl
Ga is smaller due to poor shielding of d-orbital
Q. The option(s) with only amphoteric oxides is(are) :
(A) $\mathrm{Cr}_{2} \mathrm{O}_{3}, \mathrm{BeO}, \mathrm{SnO}, \mathrm{SnO}_{2}$
(B) $\mathrm{Cr}_{2} \mathrm{O}_{3}, \mathrm{CrO}, \mathrm{SnO}, \mathrm{PbO}$
(C) $\quad \mathrm{ZnO}, \mathrm{Al}_{2} \mathrm{O}_{3}, \mathrm{PbO}, \mathrm{PbO}_{2}$
(D) $\mathrm{NO}, \mathrm{B}_{2} \mathrm{O}_{3}, \mathrm{PbO}, \mathrm{SnO}_{2}$
[JEE 2017]
Ans. (A,C)
$\mathrm{BeO}, \mathrm{Al}_{2} \mathrm{O}_{3}, \mathrm{SnO}, \mathrm{PbO}, \mathrm{Cr}_{2} \mathrm{O}_{3}, \mathrm{SnO}_{2}, \mathrm{PbO}_{2}$ are amphoteric oxides.
CrO is basic oxide , $\mathrm{B}_{2} \mathrm{O}_{3}$ is acidic oxide, NO is Neutral oxide
