The 6-membered ring compounds containing two heteroatoms, at least one of which is nitrogen, are collectively called the azines. Thiazines contain a sulfur and a nitrogen atom in the ring.

Adding to the enormous diversity of organic chemistry is the fact that two carbon atoms may be connected by single bonds consisting of 2 shared electrons, double bonds composed of 4 shared …

Interactive organic-chemistry tools: predict reaction products, draw molecules, generate IUPAC names with AI, visualize mechanisms, and analyze chirality.

Sep 2, 2025 · An epoxide is a cyclic ether characterized by a three-membered ring composed of one oxygen and two carbon atoms. This triangular arrangement creates considerable ring strain, a …

Oxiranes (epoxides) are the most commonly encountered three-membered heterocycles. Epoxides are easily prepared by reaction of alkenes with peracids, usually with good stereospecificity. Because of …

We have discussed so far that rings and carbocations (essentially like anything else) have the tendency to become more stable, i.e., go into a lower energy level. So, if we combine an unstable ring with an …

An oxirene is an unsaturated three-membered ring containing two carbon atoms and one oxygen atom. Extremely strained and thus highly unstable, it has never been observed but has been studied using …

Heterocyclic compound, any of a major class of organic chemical compounds characterized by the fact that some or all of the atoms in their molecules are joined in rings containing at least one atom of an …

Both the carbon and oxygen atoms are sp 2 hybridized. The carbon atom adopts a trigonal planar geometry with bond angles close to 120°, while the oxygen atom forms one σ bond with carbon, one …

Both the carbon and oxygen atoms are hybridized sp2, so the system is planar. The three oxygen sp2 AO’s are involved as follows: The two unshared electorn pairs of oxygen occupy two of these AO’s, …
