What is the type of molecule for $SF_4$ among $AB_4$,$AB_4E$,and $AB_3E_2$?

What is the bond angle $O-S-O$ in the $SO_2$ molecule (in $^{\circ}$)?

In order that the diagram below correctly depicts the structure of $ICl_2^-$,at what positions should the $Cl$ atoms be drawn? The central atom is $I$.

The structure of $XeF_5^-$ is:

Bond angle is minimum for

Between the dichloronitronium ion $[ONCl_2]^+$ and thionyl chloride $(OSCl_2)$,which has a higher $Cl-\hat{X}-Cl$ bond angle? (where $X$ is the central atom $N$ or $S$)
