In which of the following species, the underlined carbon atom is  ${\mathrm{sp}}^{\text{3}}$ hybridised?

Which of the following is not isostructural with ${\mathrm{SiCl}}_4?$

Which of the following compounds is ${\mathrm{dsp}}^2$ hybridised?

In which of the following species, the central atom has the maximum number of lone pair of electrons ?

Among the following transformations, the hybridisation of the central atom remains unchanged in

The hybridisations of $\mathrm{N},\mathrm{C}$ and $\mathrm{O}$ shown in the following compound

respectively, are
 

The hybridisation of xenon atom in ${\mathrm{XeF}}_4$ is

The hybridization of $\mathrm{N}$ in ${\mathrm{NO}}_2^{+}, {\mathrm{NO}}_3^{-}$ and ${\mathrm{NH}}_4^{+}$, respectively is

The hybridization of $\mathrm{Xe}$ in ${\mathrm{XeO}}_3$ is

Hybridization involved in ${\mathrm{H}}_2\mathrm{O}$ is

Hybridisation of both 'c' in acetylene molecule 

In acetylene molecule, there are

Hybridisation of ${\mathrm{C}}_2$ and ${\mathrm{C}}_3$ of  are :-

The bond angles formed by different hybrid orbitals are in the order:

Which of the following is the correct order regarding the electronegativity of hybrid orbitals of carbon?

In an octahedral structure, the pair of d-orbitals involved in ${\mathrm{d}}^2{\mathrm{sp}}^3$ hybridisation is

Assertion. ${\mathrm{BF}}_3$ molecule is planar but ${\mathrm{NF}}_3$ is pyramidal.

Reason. $\mathrm{N}$ atom is smaller than $\mathrm{B}$

Assertion. ${{\mathrm{NO}}_3}^{-}$ is planar while ${\mathrm{NH}}_3$ is pyramidal.

Reason. $\mathrm{N}$ in ${{\mathrm{NO}}_3}^{-}$ has ${\mathrm{sp}}^2$ and in ${\mathrm{NH}}_3$ has ${\mathrm{sp}}^3$ hybridization.
