Structure and Bonding
... Delocalization occurs in 1,3-butadiene where there are alternating single and double bonds. All four carbons in 1,3-butadiene are sp2 hybridized and so each of these carbons has a half-filled p orbital which can interact to give two π bonds. However, a certain amount of overlap is also possible be ...
