Current Question (ID: 10901)

Question:

$\text{O}_2\text{NCH}_2\text{CH}_2\text{O}^- \text{ is more stable than } \text{CH}_3\text{CH}_2\text{O}^- \text{ because:}$

Options:

1. $\text{NO}_2 \text{ shows +I effect}$
2. $\text{NO}_2 \text{ shows -I effect}$ (Correct)
3. $\text{NO}_2 \text{ decreases the positive charge on the compound}$
4. $\text{Ethyl group increases positive charge on the compound}$

Solution:

$\text{Hint: -NO}_2 \text{ group is an electron-withdrawing group.}$ $\text{Step 1:}$ $\text{-NO}_2 \text{ shows -I effect, it withdraws the electrons toward itself and decreases the negative charge on the compound.}$ $\text{Thereby stabilizing it. On the other hand, an ethyl group is an electron-releasing group. Hence, the ethyl group shows a +I effect and destabilize the negative charge.}$ $\text{Step 2:}$ $\text{O}_2\text{NCH}_2\text{CH}_2\text{O}^- \text{ is more stable than } \text{CH}_3\text{CH}_2\text{O}^- \text{ because of -I effect of the nitro group.}$
