[JEE 2000]

Sol. (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]

Sol. (B)


Q. The $\mathrm{IE}_{1}$ of Be is greater than that of B.

[JEE 2001]

Sol. 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]

Sol. (B)


Q. Identify the least stable ion amongst the following:

(A) $\mathrm{Li}^{-}$

(B) $\mathrm{Be}^{-}$

(C) $\mathrm{B}^{-}$

(D) $\mathrm{C}^{-}$

[JEE 2016]

Sol. (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]

Sol. (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]

Sol. (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
