Yes.
The alpha protons on the methyl group will be deprotonated and react with halides and eventually form a trihaloform group or (-C-CX3). The Trihalofrom is explelled when a OH group attacks the carbonyl carbon. This forms the trihaloform carbanion of the carboxylic acid. The anion takes a hydrogen from the acid to form the haloform and a carboxylic salt
Yes, vanillin can give a positive iodoform test. The iodoform test is used to detect the presence of a methyl ketone group attached to a carbon atom adjacent to two other carbon atoms, and vanillin has a structure that can undergo this reaction.
Reducing sugars, such as glucose and fructose, give a positive reaction with Benedict's reagent. When heated, these sugars reduce the copper (II) ions in the reagent to form a colored precipitate, indicating the presence of reducing sugars. Non-reducing sugars, like sucrose, will not give a positive reaction with Benedict's reagent.
The phenolic and tyrosine residues in proteins give a positive test with Millon's reagent. This reaction is based on the oxidation of phenolic groups by mercuric nitrate in the reagent to form a red-colored complex.
No, methanol will not give a positive result in the iodoform test. The iodoform test is specifically used to detect the presence of compounds with the CH3CO- group in them, such as methyl ketones, which are required for a positive reaction.
An entropy-driven reaction is one where the products have higher entropy than the reactants. An enthalpy-driven reaction is one where the products have lower enthalpy than the reactants. If both the entropy and enthalpy of the products are more favorable than the reactants, it is driven by both enthalpy and entropy.
Yes, vanillin can give a positive iodoform test. The iodoform test is used to detect the presence of a methyl ketone group attached to a carbon atom adjacent to two other carbon atoms, and vanillin has a structure that can undergo this reaction.
Carbohydrates typically give a positive reaction to the Molisch test. This is because the Molisch reagent reacts with the carbohydrates to form a purple complex, indicating the presence of sugar molecules in the solution.
Reducing sugars, such as glucose and fructose, give a positive reaction with Benedict's reagent. When heated, these sugars reduce the copper (II) ions in the reagent to form a colored precipitate, indicating the presence of reducing sugars.

A positive change in enthalpy for a chemical reaction indicates that the reaction is endothermic, meaning it absorbs heat from its surroundings. This typically results in the surroundings feeling cooler.
No, methanol will not give a positive result in the iodoform test. The iodoform test is specifically used to detect the presence of compounds with the CH3CO- group in them, such as methyl ketones, which are required for a positive reaction.
Negative: they bite... not only that but they may also give some allergic reaction to one's body after they attack...

If both the entropy and enthalpy of the products are more favorable than the reactants, it is driven by both enthalpy and entropy.
Alkenes and alkynes will give a positive bromine test. The reddish-brown color of a bromine solution will be decolorized upon reaction with an alkene or alkyne due to the formation of a colorless dibromo compound.
Phenylalanine. When phenylalanine is subjected to a xanthoproteic test, it will produce a yellow solution due to the reaction of the aromatic ring with nitric acid, indicating the presence of phenyl group in the tripeptide.
Acetaldehyde can be converted to butane-1,3-diol in a two-step process. First, acetaldehyde is reduced to 1,3-propanediol using a reducing agent like sodium borohydride. Then, 1,3-propanediol can be dehydrated to form butane-1,3-diol using an acid catalyst, such as sulfuric acid.
It means the person is wanting to give reaction to the weather. He/She wants to give reaction about the day.
