Total number of lone pair$(s)$ in the $XeO_2F_2$ molecule is:

The molecular shapes of $SF_4$,$CF_4$,and $XeF_4$ are:

The bond angle in $A$ is $X$ and the bond angle in $B$ is $Y$. What are $X$ and $Y$?

$A$	$B$
$CH_3OH$	$CH_3OCH_3$

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.

In which of the following pairs,the central atoms have the same number of lone pairs of electrons?

Match the following:

$A$. $SnCl_2$	$I$. Trigonal planar
$B$. $NH_3$	$II$. Linear
$C$. $I_3^{-}$	$III$. Angular
$D$. $SO_3$	$IV$. Trigonal pyramidal

The correct answer is:
