Pubchem page shows its structure is planar.. In a planar structure, obviously there will be 8 (= $4n$) pi electrons in conjugation, making it antiaromatic, contrary to what Wikipedia says. Also, I feel the molecule has a decent chance to break antiaromaticity by becoming non …
Observation of All-Metal Aromatic Molecules Science
Web2 feb. 2001 · Aromaticity is a concept invented to account for the unusual stability of an important class of organic molecules: the aromatic compounds. Here we report experimental and theoretical evidence of aromaticity in all-metal systems. A series of bimetallic clusters with chemical composition MAl4- (M = Li … WebAlkanes, alkenes, and alkynes are all classified as hydrocarbons, because they are composed solely of carbon and hydrogen atoms. Alkanes are said to be saturated hydrocarbons, because the carbons are bonded to the maximum possible number of hydrogens – in other words, they are saturated with hydrogen atoms. lite bite foods gurgaon
