The iodoform test is a chemical test that can differentiate between ethanal and propanone. Ethanal will give a positive iodoform test result, forming a yellow precipitate of iodoform (CHI3) when treated with iodine in the presence of a base like NaOH. Propanone will not give a positive iodoform test result.

What is the reaction between glucose and acidified potassium dichromate and Chemical Equation?
The reaction between glucose and acidified potassium dichromate is the oxidation of glucose to form gluconic acid. The chemical equation for this reaction is: C6H12O6 + H2Cr2O7 + H+ -> C6H11O7COOH + Cr2(SO4)3 + H2O
Structure of ethanal?
The chemical structure of ethanal, also known as acetaldehyde, consists of a carbonyl group (C=O) bonded to a single hydrogen atom, with the carbon atom also bonded to one methyl group (CH3). The molecular formula is CH3CHO.
What are the Reactions of ethanal with potassium permanganate?
Ethanol (CH3CH2OHl) + KMnO4 ----> Ethanal (CH3CHO) -----> Ethanoic Acid (CH3COOH) Primary Alcohol Oxidized ---> Aldehyde Oxidized---> Carboxyilic Acid You could attain Ethanal by using the oxidizing agent Pyridinium Chlorochromate (PCC) anhydrously.
Which statement describes a chemical property that can be used to distinguish between Compound A and Compound B?
One statement to distinguish between Compound A and Compound B based on a chemical property could be their reactivity with acid. If Compound A reacts with acid to produce a gas, while Compound B does not, this difference in chemical behavior can be used to differentiate between the two compounds.
What are the properties of the substances?
Properties of substances refer to their characteristics that can be observed or measured, such as color, density, solubility, melting point, boiling point, and chemical reactivity. These properties are used to identify and differentiate between different substances. Additionally, properties can be classified into physical (observable without changing the substance's identity) and chemical (characteristic behaviors in chemical reactions).

What are the chemical tests to distinguish between propanol and propanone benzaldehyde and benzoic acid propanoic chloride and propanoic acid also what are the reactions involved?
To distinguish between propanol and propanone, you can use the iodoform test. Propanone will give a positive iodoform test forming a yellow precipitate, while propanol will not react. For benzaldehyde and benzoic acid, adding NaHCO3 will effervesce with benzoic acid but not with benzaldehyde due to acidity. To differentiate between propanoic chloride and propanoic acid, adding water will form propanoic acid (carboxylic acid) while propanoic chloride (acid chloride) will liberate HCl gas forming a white precipitate. The key reactions involved are iodoform reaction (C3H6O +I2 + NaOH) and acid-base reactions with sodium bicarbonate and water.

The reaction between glucose and acidified potassium dichromate is the oxidation of glucose to form gluconic acid. The chemical equation for this reaction is: C6H12O6 + H2Cr2O7 + H+ -> C6H11O7COOH + Cr2(SO4)3 + H2O
what is the outcome of tollens reagent reacting with methanal, ethanol and propanone?
The outcome of the Tollens reagent reacting with methanal (formaldehyde), ethanol (ethyl alcohol), and propanone (acetone) is the formation of metallic silver (Ag) in the case of methanal, while ethanol and propanone do not show a significant reaction with Tollens reagent. Tollens reagent is used as a chemical test to distinguish between aldehydes and ketones, where aldehydes react to produce a silver mirror, while ketones do not react.
Main reason for the difference in boiling points of Methanal and Ethanal?
The main reason for the difference in boiling points between methanal (formaldehyde) and ethanal (acetaldehyde) is the difference in molecular weight and size. Ethanal has a larger molecular size and weight compared to methanal, which leads to stronger intermolecular forces such as van der Waals forces, resulting in a higher boiling point for ethanal.
What is the difference between Fertilisers and Bio-fertilisers?
The difference is that chemical fertilizers have chemicals. And bio fertilizers don't.
How can you differentiate between steel and diamond?
It is very easy to differentiate between diamond and steel. They have a completely different appearance, and a completely different chemical composition, and very different physical properties. I don't think that anyone gets these things confused.

Can you give some example sentences using the word 'differentiate'?
It's important to differentiate between right and wrong. She could not differentiate between the two identical twins. The new software features were designed to help differentiate their product from competitors. The expert could easily differentiate authentic artwork from fakes.
Differentiate between carbon dioxide and carbon monoxide?
Carbon dioxide is CO2. There is no such chemical as carbon mono dioxide, but carbon monoxide is CO.

Why does propanone have no effect on salt?
Propanone (acetone) does not have any effect on salt because acetone is a non-polar solvent, while salt is an ionic compound. Non-polar solvents like acetone cannot dissolve ionic compounds like salt due to their different types of chemical bonding. The lack of similar interactions between the solvent and solute prevents any noticeable effect on the salt.
