sp2centra
Sp2centra is a term used in chemistry to describe atoms in a molecule that are sp2-hybridized. An sp2 center uses three sp2 hybrid orbitals to form sigma bonds and may bear a lone pair, leaving one unhybridized p orbital for pi bonding. This arrangement gives a trigonal planar geometry with bond angles close to 120 degrees, and the center lies in a single plane with its substituents.
Common examples include carbon atoms in alkenes (C=C) and in carbonyl groups (C=O) such as aldehydes, ketones,
Spectroscopically, sp2 centers show characteristic signals: 13C NMR shifts for sp2 carbons typically fall roughly in
Reactivity is dominated by the pi bond: sp2centra participate in electrophilic additions to alkenes, nucleophilic additions
In summary, sp2centra denotes atoms with sp2 hybridization that create planar, pi-bonded centers central to the
