Question:
Which of the two: OO₂NCH₂CH₂O- or CH₃CH₂O- is expected to be more stable and why?

Answer:

NO₂ group is an electron-withdrawing group. Hence, it shows -I effect. NO₂group decreases the negative charge on the compound by withdrawing electrons towards it and stabilising it. On the other hand, ethyl group is an electron-releasing group. Hence, the ethyl group shows +I effect. This increases the negative charge on the compound, thereby destabilising it. Hence, O₂NCH₂CH₂O^-is expected to be more stable than CH₃CH₂O^-.
