Compare the bond lengths of the indicated bonds in the given compounds :
Options:
Answer:
A
Solution:
Both bonds are C-N bonds. In the second compound the N lone pair is pushed through the C=C onto the CHO group (a -M group, push-pull system), so the C-N bond has more double-bond character and is shorter. So a b.
