Which chemical can be used to distinguish between acetic acid and phenol?

NaHCO3 test: When both are reacted with NaHCO3, acetic acid gives brisk effervescence due to liberation of CO2 gas. But phenol does not give any reaction with NaHCO3.

Does acetic acid give Fehling test?

CH3COOH(acetic acid) cannot reduce Fehling solution whileHCOOH,HCHOand CH3CHOreduce Fehling solution due to the presence ofCHOgroup.

Does formic acid give tollens test?

Formic acid has both aldehydic (-CHO) and carboxylic (-COOH) functional groups. Hence, it gives both Tollen’s and Fehling’s test positive.

Does formic acid give 2/4 DNP test?

Yes it does. Formic acid has both a carboxyl group and a hydroxyl group, making it able to act as both a carboxylic acid and an aldehyde.

What is Fehling’s reagent Class 12?

So, Fehling solution is a mixture of copper sulphate, potassium sodium tartrate, and sodium hydroxide. It is used to differentiate between water-soluble carbohydrates (aldehyde) and ketone functional groups and as a test for reducing sugar.

How will you distinguish between phenol and benzoic acid?

Solution 2 Benzoic acid and Phenol : Benzoic acid and phenol can be distinguish by FeCl3 tests. Both reacts with FeCl3 to give different colours. Phenol reacts with FeCl3 to give violet coloured precipitate while benzoic acid give buff coloured precipitate.

Which reagent is used to distinguish between Methanoic acid and ethanoic acid?

So, tollen’s reagent i.e. ammoniacal silver nitrate solution can be used to differentiate between methanoic acid and ethanoic acid. Tollen’s reagent can be reduced by methanoic acid but it is not reduced by ethanoic acid. Therefore, option A is correct.

What test distinguish between formic acid and acetic acid?

One way to distinguish between formic acid and acetic acid is Tollen’s test. This test is also known as the silver mirror test. Formic acid gives Tollens test whereas acetic acid does not give this test. Tollen’s reagent is an ammoniacal silver nitrate solution.

What is the difference between formic acid and acetic acid?

Formic acid and acetic acid are the simplest carboxylic acid compounds. The key difference between formic acid and acetic acid is that the formic acid contains a carboxylic acid group attached to a hydrogen atom whereas acetic acid has a methyl group attached to a carboxylic acid.

How can you differentiate between formic acid and acetic acid?

Does carboxylic acid give 24 DNP test?

2,4-DNPH does not react with amides, esters or carboxylic acids. As shown below for the case of an ester, an extra resonance structure can be drawn for these 3 types of compounds as compared to a ketone.
