The structure of $S_2Cl_2$ is analogous to:

Which of the following possess two lone pairs of electrons on the central atom and are square planar in shape?
$I. SF_4, II. XeO_4, III. XeF_4, IV. ICl_4^-$

The bond angle of water is $104.5^{\circ}$ due to

The bond angle in $NF_{3}$ $(102.3^{\circ})$ is smaller than $NH_{3}$ $(107.2^{\circ})$. This is because of

Which of the following molecules has the smallest bond angle?

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 $^{\circ}$)
