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.
