Reasonable Structures,Double Bonds So far,we have only used the single bond ()which stands for two electrons.However,sometimes this bond will not work. ·Consider"o4::O 0· Is this O.K.?Well,yes and no. But instead of"O4",we can draw O2 with a double bond: double bond 4 e total,2 e per line Note that each oxygen has 8 electrons,so O2 is stable Each (-still stands for 2 e--2 lines means 4e-in bond V-11Reasonable Structures, Double Bonds So far, we have only used the single bond (—), which stands for two electrons.
