Answer:

Hydrogen cyanide is a molecular species with a relatively high boiling point of #25.6# #""^@C#.

Explanation:

As #HC-=N# is a water-like solvent, it has a relatively high boiling point, in which hydrogen-bonding is manifest as a potent intermolecular force. Of course, hydrogen cyanide is exceptionally soluble in water, where it behaves as a weak Bronsted acid....

#HC-=N(aq) + H_2O(l) rightleftharpoonsH_3O^+ + ""^(-)C-=N#

#K_a=6.17xx10^-10#...
