In ${\mathrm{H}}_2\mathrm{O},$ the bond angle $\mathrm{H}-\mathrm{O}-\mathrm{H}$ is $104°{28}^{\text{'}}$ but in ${\mathrm{H}}_2 \mathrm{S}, {\mathrm{H}}_2\mathrm{Se}$ and ${\mathrm{H}}_2\mathrm{Te}.$ the bond angles are pretty close to $90°.$ This suggests that :-

${\mathrm{XeOF}}_4$ contains :-

The $\mathrm{H}$ bond in solid $\mathrm{HF}$ can be best represented as :

$\mathrm{T}$-shape is exhibited by molecule:

$\mathrm{Li}\left[{\mathrm{AlH}}_4\right]$ is used as a reducing agent in many reaction & it is prepared by excess $\mathrm{LiH}$ and ${\mathrm{AlCl}}_3.$ Select incorrect statement about $\mathrm{Li}\left[{\mathrm{AlH}}_4\right]$

The formal charges on the three $\mathrm{O}$ -atoms in ${\mathrm{O}}_3$ molecule are

Which of the following species are hypervalent -

$1. {\mathrm{AsF}}_5 2. {\mathrm{BF}}_3 3. {\mathrm{SF}}_6, 4. {\mathrm{CO}}_3^{2-}$

Of the following isoelectronic $\&$ isostructural species are
