Conclusion
Annulenes are a type of organic compound that has a cyclic structure with alternating double and single bonds. These compounds are important in organic chemistry as they exhibit unique properties that make them useful in various applications.
Definitions
Annulenes are cyclic hydrocarbons that have alternating double and single bonds. They are aromatic compounds that have a planar structure and are highly stable due to their conjugated system. The number of carbon atoms in the ring determines the type of annulene.
Origin
The term “annulene” was first used in 1933 by the German chemist Erich Clar. He defined annulenes as cyclic hydrocarbons with alternating double and single bonds. The first annulene to be synthesized was benzene, which has six carbon atoms in its ring.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, annulenes are “unsaturated cyclic hydrocarbons having alternating double and single bonds.” The Oxford dictionary defines annulenes as “cyclic hydrocarbons with alternating double and single bonds, which are often aromatic and highly stable.”
Associations
Annulenes are associated with various properties such as high stability, aromaticity, and conjugation. They are used in the synthesis of other organic compounds and have applications in materials science, electronics, and pharmaceuticals.
Synonyms
Some synonyms for annulenes include cyclic hydrocarbons, aromatic compounds, conjugated systems, and unsaturated compounds.
Antonyms
There are no direct antonyms for annulenes, as they are a specific type of organic compound.
The same root words
Annulenes share the same root word with annular, which means ring-shaped or circular. This is because annulenes have a cyclic structure that forms a ring.
Example Sentences
