Match the following:

List-$I$	List-$II$
$A$. $BF_3$	$II$. Trigonal planar
$B$. $ClF_3$	$III$. $T$-shape
$C$. $NH_3$	$IV$. Trigonal pyramidal
$D$. $NH_4^+$	$I$. Tetrahedral

The correct match is:

Which of the following is the correct order of bond angles?

Give the correct order of initials $T$ or $F$ for following statements. Use $T$ if statement is true and $F$ if it is false:
$(I)$ The order of repulsion between different pair of electrons is $lp-lp > lp-bp > bp-bp$.
$(II)$ In general,as the number of lone pair of electrons on the central atom increases,the deviation of the bond angle from the normal bond angle increases.
$(III)$ The number of lone pairs on $O$ in $H_2O$ is $2$,while on $N$ in $NH_3$ is $1$.
$(IV)$ The structures of xenon fluorides and xenon oxyfluorides could not be explained on the basis of $VSEPR$ theory.
