The hybridisation of $Xe$ and the number of lone pairs of electrons on it in $XeF_6$ are

The mean values for the radial distance for different phosphorus orbitals are $3s: 0.47 \ \mathring{A}$,$3p: 0.55 \ \mathring{A}$,$3d: 2.4 \ \mathring{A}$. When $P$ is going to form $PF_5$,then these radial distances are going to become arbitrarily . . . . . . , . . . . . . and . . . . . . respectively.

In $CO_2$,$C$ is $sp$ hybridised using $s$ and $p_x$ orbitals. Then:

Which of the following contains an $sp^2$ hybridized carbon?

Which of the $C - C$ bond is strongest?

The geometry and the type of hybrid orbital present about the central atom in $BF_3$ is
