In the following resonance structures, the curved arrow indicates that electrons are shifted from
Options
- AAtom to adjacent bond in both ( A ) and ( B ) .
- Bπ bond to adjacent atom in both ( A ) and ( B ) .
- Cπ bond to adjacent atom in ( A ) and atom to adjacent bond in ( B ) .
- DAtom to adjacent bond in ( A ) and π bond to adjacent atom in ( B ) .
Correct answer
D. Atom to adjacent bond in ( A ) and π bond to adjacent atom in ( B ) .
Step-by-step solution
In the reaction A, the transfer of electron takes place from the oxygen atom to the adjacent bond between oxygen and carbon atom as the end of the row is between the bond formed. However, in reaction B, the transfer of electrons takes place from the π bond between the carbon and nitrogen atoms to the adjacent nitrogen atom.
