In $ICl_{4}^{-}$,the shape is square planar. The number of bond pair-lone pair repulsions at $90^{o}$ are

Which of the following molecules has the smallest bond angle?

Select from each set the molecule or ion having the smallest bond angle:
$(i)$ $NH_3, PH_3$ or $AsH_3$
$(ii)$ $O_3^+, O_3$
$(iii)$ $NO_2^-$ or $O_3$
$(iv)$ $X-S-X$ angle in $SOCl_2$ and $SOF_2$

The shape of the $O_2F_2$ molecule is similar to which of the following?

Given below are two statements:
Statement $I$: The number of compounds among $SO_2$, $SO_3$, $SF_4$, $SF_6$ and $H_2S$ in which sulphur does not obey the Octet rule is $3$.
Statement $II$: Among $[H_2O, ClF_3, SF_4]$, $[NH_3, BrF_5, SF_4]$, $[BrF_5, ClF_3, XeF_4]$ and $[XeF_4, ClF_3, H_2O]$, the number of sets in which all the molecules have one lone pair of electrons on the central atom is $1$.

The number of lone pairs of electrons on the central atom of $ClF_3, NF_3, SF_4,$ and $XeF_4$ respectively are:
