Compare the bond lengths of the indicated C-O bonds in the given compounds :
Options:
Answer:
C
Solution:
In b the C-O bond is a pure single bond and is the longest. In a the oxygen lone pair is delocalised into the ring, which gives the C-O bond partial double-bond character. In c the CHO group (-M) increases this delocalisation, so its C-O bond is the shortest. b a c.
