question 71

Multiple Choice

Which resonance state contributes most to the observed electrophilic reactivity of imines?

• A)the imine,because it's the most stable resonance form
• B)the imine,because the positive site contains a complete octet
• C)the carbocation,because it's the least stable resonance form
• D)the carbocation,because the positive site contains an open p orbital
