Draw the Lewis structure for sulfur dioxide, SO2, which does not require expanded octets. Which of the statements below is true for the Lewis structure of the SO2 molecule that obeys the octet rule?
Well, there is more than one answer... should be both
Two single bonds around sulfur use up
#"1 bond" xx "2 electron groups" xx "2 electrons" = 4#electrons,
and each oxygen holds
#"2 atoms" xx 2 xx "3 lone pairs" = 12#more electrons.
Arguably, one could construct a resonance structure where only the third lone pair on one oxygen forms a
And in fact, sulfur can do this because it has
