# In which substance does hydrogen-bonding NOT feature as an intermolecular force?

## In which substance does hydrogen-bonding NOT feature as an intermolecular force? $\text{A. nitro-phenol}$ $\text{B. hydrogen fluoride}$ $\text{C. 2,2,2-trichloroethane-1,1-diol}$ $\text{D. chlorobenzene.}$

$\text{Option D}$
Hydrogen bonding is known to occur where hydrogen is bound to a STRONGLY electronegative element, and is thus known to operate for water, i.e. $O {H}_{2}$, ammonia, $N {H}_{3}$, and for hydrogen fluoride, $H F$, and this manifests in their elevated normal boiling points that you should be able to quote.
Now $\text{chloral hydrate}$, the original $\text{mickey finn}$ is $\text{2,2,2-trichloroethane-1,1-diol}$ certainly fulfils the given criterion. So does $H F$, and so does the phenol derivative.
We are left with chlorobenzene as the solvent in which $\text{hydrogen-bonding}$ does not operate.
