Temperature is the effective factor.
When it comes to dehydration of alcohols the optimum temperature is between 220 to 250 degrees. Then it will form ether.
R-CH2-CH2-OH → R-CH+CH2 +H2O
The reaction takes place in the presence of Al2O3 at 350 to 380 degrees.

Hydrocarbons can be described as organic compounds that consists only hydrogen and carbon atoms. These compounds are of different types and thereby have distinct natures. Hydrocarbons are colorless gases and are known for discharging faint odours. These have been categorized under four major classes named as alkynes, alkanes, alkenes, and aromatic hydrocarbons.
