Which is not a proper resonance structure for 1,3-butadiene ?
(A) 
(B) 
(C) 
(D) 
Options:
Answer:
B
Solution:
A proper contributor keeps the same number of paired and unpaired electrons as the original structure. Butadiene has all electrons paired. (B) has two unpaired electrons (a diradical), so it is not a contributor.
(C) and (D) are charge-separated contributors with paired electrons.
