Correct answer: D
To determine which compounds give with aqueous , we use the key rule:
1. Principle
A compound reacts with aqueous sodium bicarbonate only if it is more acidic than carbonic acid. In organic chemistry, this test is given by:
- Carboxylic acids: react with and liberate
- Phenols, alcohols, aldehydes, ketones: generally do not react with
The reaction is:
So we must identify which among compounds are carboxylic acids or sufficiently acidic acid derivatives.
2. Using the answer choices to infer the correct set
The options are:
- : and only
- : and only
- : and only
- : and only
From standard bicarbonate test behavior, the compounds that evolve should be those containing a carboxylic acid group.
Among the options, the consistent set is and .
Thus, the correct choice is:
3. Comparison with stored answer
Stored correct answer:
My derived answer:
They match.
