Compare the resonance energies of furan (a) and pyrrole (b). Is the resonance energy of (a) greater than, less than or equal to that of (b) ?
(a) 
(b) 
Options:
Answer:
A
Solution:
Resonance energies : furan about 16 kcal/mol, pyrrole about 21 kcal/mol. The N lone pair overlaps well and O holds its lone pair more tightly, so pyrrole gains more stabilisation. So a b.
