For the molecules $\mathrm{LiF},{\mathrm{N}}_2,{ \mathrm{K}}_2\mathrm{O}$ and ${\mathrm{ClF}}_3,$ what is the correct arrangement of bonds in order of increasing ionic character?

What should be the correct order of lattice energy values of the following alkali halides?

$\mathrm{LiCl},\mathrm{KI},\mathrm{KCl}$and $\mathrm{NaCl}$

A $\mathrm{\pi }$-bond is formed by sideway overlapping of

What will be the CORRECT order of the C-F bond distance among the following?

${\mathrm{CHF}}_3,{\mathrm{CF}}_4,{\mathrm{CH}}_3\mathrm{F}$ and ${\mathrm{CH}}_2{\mathrm{F}}_2$

There are two statements, one labelled as Assertion
(A) and the other as Reason (R). Examine both the statements carefully and mark the correct choice.
(A) The $\mathrm{O}-\mathrm{H}$ bond angle in ${\mathrm{H}}_2\mathrm{O}$ is greater than $\mathrm{S}-\mathrm{H}$ bond angle in ${\mathrm{H}}_2\mathrm{S}.$
(R) Due to larger size of $\mathrm{S}$, hydrogen bonding does not occur in ${\mathrm{H}}_2\mathrm{S}.$

The hybridization state of boron in its trihalides is

${\mathrm{CHCl}}_3$ is a polar solvent while ${\mathrm{CCl}}_4$ is a nonpolar solvent because ${\mathrm{CCl}}_4$ has

Which of the following species cannot exist on the basis of Molecular Orbital Theory?
