Multiple Choice
Which of the following represents the structure of the product formed when reacts with water in the presence of an acid catalyst?
A

B
(acetic acid)
C
(ethane)
D
(ethanol)
Verified step by step guidance1
Identify the starting material: ethylene, which has the formula \(\mathrm{C_2H_4}\) and contains a carbon-carbon double bond (an alkene).
Understand the reaction conditions: water (\(\mathrm{H_2O}\)) in the presence of an acid catalyst. This typically leads to an acid-catalyzed hydration of the alkene.
Recall the mechanism of acid-catalyzed hydration of alkenes: the double bond is protonated to form a carbocation intermediate, followed by nucleophilic attack by water, and finally deprotonation to give an alcohol.
Determine the product by adding an -OH group to one of the carbons of the original double bond and a hydrogen to the other carbon, converting the alkene into an alcohol with the formula \(\mathrm{C_2H_5OH}\) (ethanol).
Confirm that the product is ethanol, not ethane (\(\mathrm{C_2H_6}\)), acetic acid (\(\mathrm{C_2H_4O_2}\)), or unchanged ethylene (\(\mathrm{C_2H_4}\)).
