Cyclooctatetraene nonaromatic or antiaromatic
WebFeb 10, 2016 · Cyclooctatetraene is known to add bromine, and generally behave like a cyclic polyalkene in many aspects. The only cases where molecules don't escape planarity is when they cannot. This happens in the case of cyclobutadiene. Such a molecule is so small, it cannot be distorted to such extents. WebCyclooctatetraene is non aromatic in nature as it does not follow the Huckel’s rule of aromaticity which says that for a compound to be aromatic it should be cyclic,should …
