Which of the following types of hybridisation results in trigonal planar geometry?

Describe the hybridization in $PCl_{5}$. Why are the axial bonds longer as compared to equatorial bonds?

The number of $sp^{2}$ hybrid orbitals in a molecule of benzene is

Why is the bond angle in $CH_4$ not $90^{\circ}$,even though the outermost $p$-orbitals of carbon are at $90^{\circ}$ to each other?

In $Cl_2O_{6(l)} + HF \to P + Q$. If $H$ of acid $HF$ attaches with $Q$,then identify the correct option for hybridization of $Cl$ atom and $\angle OClO$ in the $P$ and $Q$ ions.

Match the following:
| List-$I$ (Molecule/ion) | List-$II$ (Hybridisation) |
| :--- | :--- |
| $(A)$ $ICl_4^-$ | $(P)$ $sp^3$ |
| $(B)$ $NO_3^-$ | $(Q)$ $sp^3d$ |
| $(C)$ $PCl_4^+$ | $(R)$ $sp^3d^2$ |
| $(D)$ $SiF_6^{2-}$ | $(S)$ $sp^2$ |
| | $(T)$ $sp$ |
