How can you tell the difference between cinnamic acid and benzoic acid?
To distinguish between benzoic acid and cinnamic acid bromine water is added to it. Benzoic acid does not react with bromine water and can not decolourise the red colour of bromine water. Cinnamic acid is an unsaturated compound. So, it easily reacts with bromine and decolourises the red colour of bromine water.
How can you tell the difference between benzoic acid and salicylic acid?
The key difference between salicylic acid and benzoic acid is that salicylic acid has a –OH group ortho to the carboxylic acid group, whereas benzoic acid has no –OH groups in its ring structure. Salicylic acid and benzoic acid are organic compounds.
How do you test for benzoic acid?
Heat the test tube over a low flame. Benzoic acid sublimes and crystals deposit in the colder part of the test tube leaving no residue at the bottom. Determine using an atomic absorption technique appropriate to the specified level.
How can you tell the difference between 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.
What is cinnamic acid derivatives?
The common cinnamic acid derivatives include p-coumaric acid, caffeic acid, and ferulic acid. Chokeberry is abundant in hydroxycinnamic acid derivatives represented mainly by chlorogenic acid and neochlorogenic acid. Hydroxybenzoic acid is the most abundant phenolic acid in cranberry followed by hydroxycinnamic acid.
How do you prepare the derivative of benzoic acid?
The method comprises the following step: hydrolyzing a cyanobenzene derivative in an aqueous reaction mixture to generate the benzoic acid derivative under the action of an enzyme catalyst containing nitrilase, preferably, wherein the cyanobenzene derivative is selected from ammonia methyl cyanobenzene and chlorine …
How do you identify salicylic acid?
Salicylic acid is an organic compound with the formula HOC6H4CO2H. A colorless, bitter-tasting solid, it is a precursor to and a metabolite of aspirin (acetylsalicylic acid).
How do you test for salicylic acid?
Salicylic acid, the major metabolite of ASA, can be detected easily in urine using simple chemical spot tests such as ferric chloride or Trinder’s reagent. In forensic cases, urine is often not available and the rapid detection of salicylate in whole hemolyzed blood can be difficult.
Is cinnamic acid saturated or unsaturated?
Cinnamic acid, an unsaturated carboxylic acid, is the chief constituent of the fragrant balsamic resin storax.
How do you identify phthalic acid?
Phthalic acid is an aromatic dicarboxylic acid, with formula C6H4(CO2H)2. It is an isomer of isophthalic acid and terephthalic acid….Phthalic acid.

Which test distinguish between benzoic acid and phthalic acid?
1. If Heating on a porcelain piece gives sooty flame then it’s pthalic acid and if it’s non sooty then it is oxalic acid… because sooty flames are given by aromatic compound pthalic acid is aromatic compound while oxalic acid is aliphatic. 2.
How can you tell the difference between propanal and propanone?
Propanal and Propanone : These two are distinguished by the iodoform test. propanal does not give iodoform test when it reacts with I2 in the presence of NaOH while propanone give iodoform test when reacts with I2 in the presence of NaOH.
