Who gave the principle of $VSEPR$?

When iodine is dissolved in aqueous potassium iodide,the shape of the species formed is

Match the following:
$($Molecule$/$Ion$)$  $($Shape$)$
$A. I_3^- \rightarrow  4.$ Linear  
$B. ClF_3 \rightarrow  1.$ $T-$shaped  
$C. H_2O \rightarrow  3.$ Angular  
$D. SF_4 \rightarrow  2.$ See$-$Saw

What is the value of the $C-O-H$ bond angle in $CH_3OH$ (in $^{\circ}$)?

Based upon $VSEPR$ theory,match the shape (geometry) of the molecules in List-$I$ with the molecules in List-$II$ and select the most appropriate option.

List-$I$ (Shape)	List-$II$ (Molecules)
$A$. $T$-shaped	$I$. $XeF_4$
$B$. Trigonal planar	$II$. $SF_4$
$C$. Square planar	$III$. $ClF_3$
$D$. See-saw	$IV$. $BF_3$

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