Hybridisation of $\mathrm{Al}$ in ${\mathrm{AlCl}}_3$ (monomeric form above $800°\mathrm{C}$) and ${\mathrm{Al}}_2{\mathrm{Cl}}_6$ (dimeric form below $400°\mathrm{C}$) respectively are

Which one of the following statements about carbon monoxide is correct? 

Which one of the following statements about water is false?

In which of the following molecule would you expect the nitrogen to nitrogen bond to be longest?

Which of the following species is not paramagnetic?

Which one of the following pairs of species have the same bond order?

Consider the following statements:

${\mathrm{S}}_1$: ${\mathrm{N}}_2{\mathrm{H}}_4$ is pyramidal about each $\mathrm{N}$ atom.

${\mathrm{S}}_2$: ${\mathrm{NH}}_2\mathrm{OH}$ is pyramidal about the $\mathrm{N}$ atom and bent about the $\mathrm{O}$ atom.

${\mathrm{S}}_3$: ${\mathrm{CH}}_3\mathrm{COCl}$ is trigonal about the carbon atom (attached to $\mathrm{O}$ and $\mathrm{Cl}$).

Out of these, select the correct one.

Which of the following statement is true for ${\mathrm{IO}}_2{\mathrm{F}}_2^{-}$?
