The isostructural molecules among $CO_2, SiO_2, SO_2, TeO_2, [NO_2]^{+}$ are

Identify the molecule $(X)$ with the maximum number of lone pairs of electrons (obtained using Lewis dot structure) among $HNO_{3}$, $H_{2}SO_{4}$, $NF_{3}$, and $O_{3}$. Choose the correct bond angle made by the central atom of the molecule $(X)$. (in $^{\circ}$)

In which of the following is the $O-N-O$ bond angle highest?

The correct increasing order of the number of lone pairs of electrons on the central atom of $SnCl_2$,$XeF_2$,$ClF_3$,and $SO_3$ is:

The molecule $ML_x$ is planar with $7$ pairs of electrons around $M$ in the valence shell. The value of $x$ is
