Question

write dehydration reactions of alcohols by using H2 So4 at different concentration​

Answer 1

Answer:

The required range of reaction temperature decreases with increasing substitution of the hydroxy-containing carbon:

1° alcohols: 170° - 180°C

2° alcohols: 100°– 140 °C

3° alcohols: 25°– 80°C

If the reaction is not sufficiently heated, the alcohols do not dehydrate to form alkenes, but react with one another to form ethers
