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

What components of protein give a positive test with Millon's reagent and on what is this reaction based?
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.
Does vanillin gives iodoform test?
No because vanillin is phenolic aldehyde (only acetaldehyde give idoform among all ketones)
How do you know if a reaction is entropy driven enthalpy driven or driven by both enthalpy and energy?
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.
Why phenol do not give protonation reaction readly?
Electron density on oxygen in phenoxide ion is decreased due to resonance. The oxygen rather acquire a positive charge. Therefore phenol does not give protonation readily
Which carbohydrates give a positive reaction with benedicts reagent?
all reducing sugars - monosaccharides like glucose and a few non-reducing disaccharides like maltose

What does it mean if the change in enthalpy value for a chemical reaction is positive?
Change in enthalpy value for a chemical reaction is positive is because,there loose of electron(s) in the reaction, and that will change the enthalpy of that particular element from negetive,neutral to positive.
Does vanillin gives iodoform test?
No because vanillin is phenolic aldehyde (only acetaldehyde give idoform among all ketones)
What positive and negative qualities do insects have?
Negative: they bite... not only that but they may also give some allergic reaction to one's body after they attack...

What tripeptide will give a positive xanthoproteic test?
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.
How do you convert acetaldehyde to butane-1 3-diol?
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.
What is the meaning of look to this day and give an reaction?
It means the person is wanting to give reaction to the weather. He/She wants to give reaction about the day.
