Which of the following statements is true of ?
A
is an aromatic compound.
B
contains an amine functional group.
C
contains both an alcohol and a geminal diol functional group.
D
is classified as a carboxylic acid.
Verified step by step guidance1
Step 1: Understand the structure of chloral hydrate. Chloral hydrate is formed by the addition of water to chloral (trichloroacetaldehyde), resulting in a geminal diol where two hydroxyl groups are attached to the same carbon atom.
Step 2: Analyze the functional groups present. Since chloral hydrate has two hydroxyl (–OH) groups on the same carbon, it contains a geminal diol functional group. Each hydroxyl group is also an alcohol functional group.
Step 3: Evaluate the other options. Chloral hydrate is not aromatic because it lacks a conjugated ring system; it is not an amine because it contains no nitrogen atoms; and it is not a carboxylic acid because it does not have a carboxyl (–COOH) group.
Step 4: Conclude which statement is true based on the functional groups identified. The presence of both alcohol and geminal diol groups is the correct characterization of chloral hydrate.
Step 5: Summarize the reasoning: chloral hydrate is best described as a compound containing both an alcohol and a geminal diol functional group, distinguishing it from aromatic compounds, amines, and carboxylic acids.
