Preparation of ethers by 2 or 3-degree alcohols in an acidic medium is not a suitable method because:
1. | In case of secondary or tertiary alcohols, ketone is obtained as a product. |
2. | In case of secondary or tertiary alcohols, aldehyde is obtained as a product. |
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. |
