Multiple Choice
Which of the following compounds is considered a strong acid in organic chemistry?
A
Ammonia (NH3)
B
Acetic acid (CH3COOH)
C
Phenol (C6H5OH)
D
Hydrochloric acid (HCl)
Verified step by step guidance
1
Identify the nature of each compound listed: Ammonia (NH3) is a weak base, Acetic acid (CH3COOH) is a weak acid, Phenol (C6H5OH) is a weak acid, and Hydrochloric acid (HCl) is a strong acid.
Understand the concept of acid strength: In organic chemistry, a strong acid is one that completely dissociates in water, releasing a high concentration of hydrogen ions (H+).
Compare the dissociation of each compound in water: Ammonia does not dissociate to release H+ ions, Acetic acid partially dissociates, Phenol partially dissociates, and Hydrochloric acid completely dissociates.
Recognize that Hydrochloric acid (HCl) is a mineral acid, which is typically stronger than organic acids like Acetic acid and Phenol.
Conclude that among the given options, Hydrochloric acid (HCl) is the compound considered a strong acid in organic chemistry due to its complete dissociation in water.
