Answer: The molecules are and
.
Explanation:
Hydrogen bonding is defined as weak electrostatic force present between the hydrogen atom on one molecule with neighboring electro-negative atom of an other molecule. Usually oxygen nitrogen and fluorine atoms forms hydrogen bonding when present in a molecule of a compound.
From the given compounds , compound with any atom out of oxygen nitrogen and fluorine will form hydrogen bonding with the hydrogen atom present in a molecule adjacent to them.

Explanation:
Yes, a chemical reaction can happen with only one substance.
A typical example of such reaction is the radioactive decay.
Radioactive decay is the loss of elementary particles from an unstable nucleus, ultimately changing the unstable element into another more stable element. .
When radioactive elements are let alone, they decompose to form stable harmless elements.
An example of radioactive decay is attached in the image below;
