The presence of lone pair of electrons on nitrogen are delocalised towards the ring as the lone pair is in conjugation with the doublebond. Further, the methyl group on nitrogen is an electron donating group and activates the nitrogen by pushing electrons towards nitrogen by hyperconjugation.
However in dihydro furan, the electrons constituting the double bond are delocalised away from the ring and towards oxygen, as oxygen is highly electronegative than nitrogen

Explain why, in a market with negative externality, too much output (more than the efficient amount) is produced and sold and positive externality, too little output (less than the efficient amount) is produced and sold. If you use a diagram in your answer, make that diagram large and label all axes, curves, and points.
