In the first chapter of Solomon's text book there are exercises for resonance structures. One of the answers to one of the exercises suggests that 1-bromoethene  has resonance structures.
 
[ CH3-S+=CH2  :resonance:CH3-S-CH2+]
And the answer is with a hybridized bond between the sulfur and the carbon. I don't understand why this would be the case. I didn't think that the structure with the charged carbon would be a meaningful resonance structure, and that the sulfur given its size would be better able to hold the charge.
