Compare the bond lengths of the indicated bonds in the given compounds :
Options:
Answer:
A
Solution:
Bond a is a terminal C=C of a linearly conjugated triene, so its electrons are delocalised over the whole chain and it has some single-bond character. Bond b is a C=C in a cross-conjugated system, where the delocalisation is poorer. So bond a is longer : a b.
