The number of species having a non-pyramidal shape among the following is:
$A$. $SO_{3}$
$B$. $NO_{3}^{-}$
$C$. $PCl_{3}$
$D$. $CO_{3}^{2-}$

Which of the following has a tetrahedral shape?

The shape of ethane $(C_2H_6)$ is........

Given below are two statements:
Statement $(I) :$ For $ClF_3$,all three possible structures may be drawn as follows:
(Image provided)
Statement $(II) :$ Structure $III$ is most stable,as the orbitals having the lone pairs are axial,where the $\ell p-bp$ repulsion is minimum.
In the light of the above statements,choose the most appropriate answer from the options given below:

The number of bond pairs,lone pairs present on the central atom of $SF_4$ molecule and its shape respectively are

The equatorial and axial $P-Cl$ bond lengths (in $pm$) respectively in $PCl_5$ are:
