The bond angle between two hybrid orbitals is $105^{o}$. The $\%$ $s-$orbital character of the hybrid orbital is:

In which of the following compounds will the angle between two covalent bonds be the largest?

Which compound of sulphur is formed in the second excited state?

The hybridisation of $C$ in diamond,graphite and ethyne is in the order

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.

Match the compounds given in $Column\, I$ with the hybridisation and shape given in $Column\, II$ and mark the correct option.

$Column\, I$	$Column\, II$
$(A)\, XeF_6$	$(i)\, \text{Distorted octahedral}$
$(B)\, XeO_3$	$(ii)\, \text{Square planar}$
$(C)\, XeOF_4$	$(iii)\, \text{Pyramidal}$
$(D)\, XeF_4$	$(iv)\, \text{Square pyramidal}$
