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 |
Preparation of ethers by 2 or 3-degree alcohols in an acidic medium is not a suitable method because:

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. |
