What are the limitations to prepare ether by this method?
उत्तर
Limitations:
- When alcohol is heated with dehydrating agents like concentrated H2SO4 or H3PO4 two products, either ether or an alkene can form depending upon the temperature.
- Use of higher temperature or 2°/3° alcohols gives alkene as the major product.
