Which of the following is the correct bond-line structure for (CH3)2N(CH2)3CH(CH3)2 ? II III V I II III IV V Which of the following pairs are resonance structures of each other? I. II. Why is the single curved arrow shown insufficient to draw a resonance structure? The resulting structure would have a positive on the most electronegative atom The resulting structure would have an octet rule violation The resulting structure would have a negative on the most electronegative aton The resulting structure would have a negative on the least electronegative atom The resulting structure would have an atom with less than an octet For the structure shown in the box below identify a corresponding correct resonance structure
