Tollens are chemical reagents that are commonly used to determine whether a known carbonyl containing compound is an aldehyde. It is stated that CH3CHO will not react to tollens at all.

Equation for the reaction of ethanal with Tollens reagent?
2[Ag(NH3)2]+ + CH3CHO + 3OH- --> 2Ag + 2H2O + 4NH3 + CH3COO-
Why Tollens reagent does not react with ketone?
because
Does tollens reagent react with cyclohexanone?
yes!!
What is the reaction of acetone and tollens reagent?
Tollens' reagent is used to determine whether a carbonyl containing compound is an aldehyde or a ketone. Acetone is a ketone so it will not readily react with Tollens' reagent.
Is vanillin positive in tollens test?
No.While vanillin is an aldehyde, which should react with Tollens' reagent to precipitate silver metal, vanillin does not "pass" Tollens' test. Tollens' reagent is very basic (sodium or potassium hydroxide). Vanillin has a phenolic hydrogen (OH bonded to a phenyl ring) which is slightly acidic. Vanillin will react first with the excess hydroxide ions in solution to form a phenoxide salt, which will not participate in the silver-precipitating reaction.

What is the equation for the reaction between tollens' reagent and butanone?
Does not react. Because Tollens' reagent only works with aldehydes. Butanone is methyl ethyl ketone (MEK).
Is vanillin positive in tollens test?

Tollens' reagent is very basic (sodium or potassium hydroxide). Vanillin has a phenolic hydrogen (OH bonded to a phenyl ring) which is slightly acidic.

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.
Molecular geometry of CH3CHO?
moelecular geometry of ch3cho
Which reagent vanillin react?
vanillin violently reacts with Bromine in carbon tetrachloride,tollens reagent and aqueous NaOH
Why pyrrole-2-aldehyde does not respond to tollens reagent?
Pyrrole-2-aldehyde does not respond to Tollens reagent because it is not a reducing sugar. Tollens reagent (silver nitrate) is used to test for the presence of aldehyde groups, which are commonly found in reducing sugars. Reducing sugars contain aldehyde groups and are capable of donating electrons to Tollens reagent, forming a silver mirror on the test tube wall. Pyrrole-2-aldehyde does not contain aldehyde groups, and therefore is not a reducing sugar. As a result, it does not react with Tollens reagent.
Ethanol CH3CHO - how to write an equation to represent the enthalpy of formation?
CH3CHO+HCl
What are the names of CH3CHO and AgNO3 and NH4OH?
CH3CHO is acetoneAgNO3 is silver nitrateNH4OH is ammonium hydroxide
