Which chemical are all phenolic chemicals a derivative of?
A
Hydroxyl.
B
Ethanol.
C
Aldehyde.
D
Phenol.
E
Benzene.
Verified step by step guidance1
Understand the structure of phenolic compounds: Phenolic chemicals are characterized by the presence of a hydroxyl group (-OH) bonded directly to an aromatic hydrocarbon group.
Identify the basic structure of phenol: Phenol is the simplest aromatic alcohol, consisting of a benzene ring bonded to a single hydroxyl group.
Recognize the relationship between phenol and other phenolic compounds: All phenolic chemicals are derivatives of phenol, meaning they are structurally related to phenol and often contain additional functional groups or modifications.
Differentiate phenol from other chemical structures: Compare phenol with other options like ethanol (a simple alcohol), aldehyde (a carbonyl compound), and benzene (a simple aromatic hydrocarbon without a hydroxyl group).
Conclude that phenol is the parent compound: Since phenolic chemicals are defined by the presence of a hydroxyl group on an aromatic ring, phenol serves as the fundamental structure from which these compounds are derived.
