ResourceFunction["RingMoleculeQ"][mol]

yields True if the molecule mol has rings, and returns False otherwise.

Details

A molecule contains rings if the underlying chemical graph contains at least one cycle.

Test if a molecule has rings:

In[1]:=

Out[1]=

Not all molecules have rings:

In[2]:=

Out[2]=

Select entities from a class of chemicals which contain rings:

In[3]:=

Out[3]=

Since these molecules have rings, their underlying Graph representations are not acyclic:

In[4]:=

Out[4]=
