WebOct 14, 2015 · The phase of the two interacting orbital (+ or -) comes from the sign of orbital wave function and is not related to the charge in any sense. Negative Overlapping of Atomic Orbital – When the phase of two interacting atomic orbital is opposite, then the overlap is negative and in this case, the bond is not formed. WebWe indicate the phases by shading the orbital lobes different colors. When orbital lobes of the same phase overlap, constructive wave interference increases the electron density. When regions of opposite phase overlap, the destructive wave interference decreases electron density and creates nodes. WebFor a carbon with 1 double bond and 2 single bonds, the orbitals will become 33% "s" and 66.7% "p" making it "sp2." If there is a triple bond and a single bond, the orbitals will adjust again to become 50% "s" and 50% "p." So to summarize - You can find sp3 bonding when a carbon has 4 single bonds. You can find sp2 bonding when carbon has a ONE ... chirurgie forst
