What is the structure of $IF_7$?

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 $^{\circ}$)

Among the following,the correct statement for thionyl tetrafluoride $(SOF_4)$ is:

The geometries of $XeF_4$ and $XeOF_4$ respectively are

Match the molecular geometries in List-$I$ with their corresponding molecules in List-$II$:

$A$. Trigonal planar	$I$. $PCl_5$
$B$. Tetrahedral	$II$. $SF_6$
$C$. Trigonal bipyramidal	$III$. $BF_3$
$D$. Octahedral	$IV$. $CCl_4$

The correct match for $A, B, C, D$ is:

Which of the following is $NOT$ tetrahedral in shape?
