Heterocyclic compounds are found in many different types of molecules, including drugs, natural products, and plastics. The rings in heterocyclic compounds can be made up of a variety of different atoms, including carbon, nitrogen, oxygen, sulfur, and phosphorus.<\/p>\n<p><img loading=\"lazy\" class=\"aligncenter wp-image-149449 size-full\" src=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2022\/03\/major-classes-of-heterocyclic-compounds-definition-and-properties.jpg\" alt=\"\" width=\"606\" height=\"428\" srcset=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2022\/03\/major-classes-of-heterocyclic-compounds-definition-and-properties.jpg?v=1647838347 606w, https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2022\/03\/major-classes-of-heterocyclic-compounds-definition-and-properties-300x212.jpg?v=1647838347 300w\" sizes=\"(max-width: 606px) 100vw, 606px\" \/><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Five_and_Six_Membered_Rings\"><\/span>Five and Six Membered Rings<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In organic chemistry, a five-membered ring is a ring of atoms with five members.

This double bond can cause the ring to be unstable, and the ring can often open up to form a new, more stable molecule. In addition, five and six-membered rings often have low polarity, meaning that the electrons in the ring are not as likely to move around as they are in larger rings. This can make the molecules more difficult to dissolve in water.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Pyridine_and_Pyrrole_-_Physical_and_Chemical_Properties\"><\/span>Pyridine and Pyrrole &#8211; Physical and Chemical Properties<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Pyridine is a nitrogen-containing heterocyclic organic compound with a six-membered ring.
