Which of the following pair constitute resonance structure?A. B. C. D. `H_(3)C-CH=CH-CH_(3)` and `H_(3)C-CH_(2)-CH=CH_(2)`

Which of the following pair constitute resonance structure?A. B. C. D.

1.	Which of the following pair constitute resonance structure?A. B. C. D. `H_(3)C-CH=CH-CH_(3)` and `H_(3)C-CH_(2)-CH=CH_(2)`
Answer» Correct Answer - b In resonance , the positive of atom remains fixed so pairs in (b) constitute resonance. In other pairs , the positive of atoms keeps changing therefore (a), ( c) and (d) do not constitute resonance
