Question 1 pts
Define the term heterocycle as it applies to organic molecules.
Your Answer:
Heterocycles (heterocyclic compounds) are cyclic organic molecules in
which one or more carbon atoms are replaced by heteroatoms – elements
other than carbon or hydrogen.

Question 2 pts
, 12/14/23, 8:43 PM Module 7 Problem Set: Principles of Organic Chemistry with Lab-2021-Gallaher
What are the two main sub-groups of heterocyclic compounds?
Your Answer:
aromatic and non-aromatic
Answer:
Aliphatic and Aromatic
Question 3 pts
Explain why pyridine is soluble in water.
Your Answer:
Pyridine can accept hydrogen bonding interactions due to the lone pair of
electrons in nitrogen. And the electronegative N creates a relatively strong
dipole moment, making it a polar compound.
Answer:
There are several factors that explain the ability of pyridine to
dissolve in water. First is the ability of pyridine to accept
hydrogen bonding interactions from water molecules due to
the lone pair of electrons on the nitrogen atom. In addition,
the electronegative nitrogen creates a relatively strong dipole
moment in the pyridine molecule, thus making pyridine a
polar compound overall.
