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?
amino acid
How do you know if a reaction is entropy driven enthalpy driven or driven by both enthalpy and energy?
If the ∆H is positive and the ∆S is positive, then the reaction is entropy driven. If the ∆H is negative and the ∆S is negative, then the reaction is enthalpy driven. If ∆H is positive and ∆S is negative, then the reaction is driven by neither of these. If ∆H is negative and ∆S is positive, then the reaction is driven by both of these.
Does vanillin gives iodoform test?
No because vanillin is phenolic aldehyde (only acetaldehyde give idoform among all ketones)
What is the synthesis of phenyl acetaldehyde from styrene oxide please give detail process?
Heat (300º?) styrene oxide in a closed system, you will obtain a mixture of styrene oxide and phenyl acetaldehyde. IIRC you can heat at reflux S.O. and some kind of silica catalyst with a solvent and obtain that same product.
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

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?
No, because phenylalanine does not react with the nitric acid in this test.
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.

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
Do proteins give positive iodine tests?
Yes it give positive result
