The shape of $O_2F_2$ is similar to which of the following?

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

What is the number of bonds and lone pairs in $SO_2$?

The shape of the $XeF_2$ molecule is ..........

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.

Which of the following molecules is not linear?
