The $\mathrm{d}$-orbital involved in ${\mathrm{sp}}^3\mathrm{d}$ hybridisation :-

The correct statement for the reaction -

${\mathrm{NH}}_3+{\mathrm{H}}^{+}\to {\mathrm{NH}}_4^{+}$

The vapor pressure of o-nitrophenol at any given temperature is predicted to be-

${\mathrm{H}}_2\mathrm{O}$ boils at higher temperature than ${\mathrm{H}}_2\mathrm{S}$ because it is capable of forming:

In solid argon the atoms are held together

In ${\mathrm{BF}}_3$, the $\mathrm{B}-\mathrm{F}$ bond length is $1.30 \stackrel{\mathrm{o}}{\mathrm{A}}$, when ${\mathrm{BF}}_3$ is allowed to be treated with ${\mathrm{Me}}_3\mathrm{N}$, it forms an adduct, ${\mathrm{Me}}_3\mathrm{N}\to {\mathrm{BF}}_3$, The bond length of $\mathrm{B}-\mathrm{F}$ in the adduct is :

The hydration of ionic compounds involves -

Among the following, which compound will show the highest lattice energy?
