$o-$nitrophenol can be easily steam distilled whereas $p-$nitrophenol cannot be. This is because of

Which one among the following does not have the hydrogen bond?

Consider the following statements:
$I.$ In gaseous phase,the vapour pressure of $CH_3COOH$ is less than expected.
$II.$ In benzene,acetic acid dimerises.
$III.$ $CH_3OH$ is more viscous than $H_2O$.
$IV.$ $CH_3OCH_3$ is non-polar but soluble in water.
Select the correct set of codes using $T$ for true and $F$ for false statements in the given sequence.

What is the maximum number of hydrogen bonds in which a water molecule can participate?

The boiling point of $p$-nitrophenol is higher than that of $o$-nitrophenol because:

The intermolecular interaction that is dependent on the inverse cube of distance between the molecules is:
