1.	If a compound contains conjugated system, the measured bond lengths differ form the expected bond length but 1, 3 diene contains following resonance structures Which of the following is correct
Answer» In 1,3 - BUTADIENE all C-atoms are `sp^(2)` Bond lengths between `C_(2)-C_(3)` is higher than `C_(1)-C_(2)` Butadiene EXHIBITS 1,4-addition as well as 1,2 - addition All the above Solution :Resonance
