The $PCl_5$ molecule is a result of the hybridisation of

When the hybridisation state of a carbon atom changes from $sp^3$ to $sp^2$ to $sp$,the angle between the hybridised orbitals

The species in which the nitrogen atom is in a state of $sp$ hybridisation is

Provide the orbital structure of ethene showing: $(i)$ $\sigma$-bond $(ii)$ $\pi$-bond $(iii)$ The number of $\sigma$ and $\pi$-bonds $(iv)$ The hybridization.

Consider the following reactions:
$(i)$ $PCl_3 + 3H_2O \to H_3PO_3 + 3HCl$
$(ii)$ $SF_4 + 3H_2O \to H_2SO_3 + 4HF$
$(iii)$ $BCl_3 + 3H_2O \to H_3BO_3 + 3HCl$
$(iv)$ $XeF_6 + 3H_2O \to XeO_3 + 6HF$
Then according to given information the incorrect statement is

Identify the molecule in which the central atom undergoes $sp^3$ hybridisation.
