The nature of hybridization in the $NH_3$ molecule is

$XeF_2$ involves which type of hybridisation?

Observe the following statements:
Statement-$I$: Hybridisation is not the same in both ${SF}_6$ and ${BrF}_5$.
Statement-$II$: ${BrF}_5$ is square pyramidal while ${SF}_6$ is octahedral in shape.
The correct answer is:

What is the hybridization and structure of $XeF_4$?

What is the correct order of carbon-carbon bond length in the following molecules?

The $C-H$ bond distance is the longest in
