In carbon, sp2 hybridization permits formation of these structures.
Compounds containing these structures resonate in the band from 1500 to 1800 wavenumbers in IR spectroscopy. In carbon, sp2 hybridization permits formation of these structures. These structures prevent rotation of adjoining groups with respect to one another, giving rise to configurations that can be described using E-Z notation, or less precisely, using cis-trans notation. They are eliminated when unsaturated fats are hydrogenated to yield saturated ones. Alkenes are defined by having at least one of these linkages between two carbons. For 10 points, name these linkages that appear in diatomic oxygen, bonds in which four electrons are shared between two atoms.
