Intermolecular Dehydration of Alcohols

question 1

(UFAM) The intermolecular dehydration reaction of an organic compound in the presence of 140 sulfuric acid^OC, produced a highly flammable liquid, less dense than water, with strong anesthetic action and sufficient non-polarity for the extraction of oils and fats. The compound and the liquid that fit these characteristics are, respectively:

a) Propanol and ethyl acetate

b) Methanol and methoxymethane

c) Acetic acid and ethyl ethanoate

d) Acetone and ethoxymethane

e) Ethanol and ethoxyethane

question 2

(FGV-SP) When ethanol is brought into contact with sulfuric acid, hot, a dehydration reaction occurs, and the products formed are related to the reaction temperature. Intramolecular dehydration occurs at 170ºC and intermolecular dehydration at 140ºC. The products of intramolecular and intermolecular dehydration of ethanol are, respectively,

a) ethane and ethoxyethene.

b) ethene and ethoxyethane.

c) ethoxyethene and ethene.

d) ethoxyethane and ethene.

e) ethoxyethene and ethane.
