The $BCl_3$ molecule is planar. What type of hybridization does the boron atom undergo in this molecule?

Which molecule has $sp^3$ hybridization of the central atom?

Explain the shape of $sp$,$sp^2$,and $sp^3$ hybrid orbitals.

Which of the following can have a structure with $sp^3$ $C$ atoms only?

The nature of hybridization in $CH_2Cl-CH_2Cl$ for carbon is:

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.
