Identify the steam-volatile compound among the following.
1. o-Nitrophenol
2. p-Nitrophenol
3. Both 1 and 2
4. None of the above
Ortho nitrophenol is more acidic than ortho methoxy phenol because:
| 1. | The NO2-group increases the electron density in phenol while the methoxy group decreases the electron density in phenol |
| 2. | The nitro-group is an electron-withdrawing group while the methoxy group is an electron-releasing group |
| 3. | The methoxy-group is an electron-withdrawing group while the nitro group is an electron-releasing group |
| 4. | None of the above |
Why is the preparation of ethers from secondary or tertiary alcohols in acidic medium generally not suitable?

| 3. | In case of secondary or tertiary alcohols, alkene is obtained as a product. |
| 4. | In case of primary alcohols, alkene is obtained as a product. |
