What is difference between functional group and molecules?
A functional group is a specific arrangement of atoms within a molecule that gives it its characteristic chemical properties. A molecule is a group of atoms bonded together, which may contain one or more functional groups. In other words, a functional group is a part of a molecule that determines its reactivity and behavior.
Why is the xanthoproteic test for phenol negative?
I reckon the answer would be that phenol has a hydroxyl group (-OH) which is bonded to a phenyl ring. It yields the same positive result like tyrosine which has a hydroxyl group bonded to its phenyl ring.
What is the functional groups of benzoic acid?
The functional group of benzoic acid is a carboxylic acid group, which consists of a carbonyl group (C=O) and a hydroxyl group (OH) attached to a benzene ring. This gives benzoic acid its acidic properties.
Is vanillin positive in DNPH test?
No, vanillin is not positive in the DNPH (2,4-dinitrophenylhydrazine) test. The DNPH test is used to detect the presence of carbonyl (aldehyde or ketone) functional groups in compounds and vanillin does not contain a carbonyl group.
What is the functional group contained in thiol?
The functional group contained in a thiol is the sulfhydryl group, which is a sulfur atom bonded to a hydrogen atom. Thiols are organic compounds that contain this sulfhydryl group, which gives them their characteristic properties such as strong odor, reactivity, and ability to form disulfide bonds.
Do albumin gives a positive xanthoproteic test?
I reckon the answer would be that phenol has a hydroxyl group (-OH) which is bonded to a phenyl ring. It yields the same positive result like tyrosine which has a hydroxyl group bonded to its phenyl ring.
Does human insulin give positive xanthoproteic test?
No because it doesn't contain aromatic group
Would adrenaline give a positive test to Xanthoproteic test?
Yes, adrenaline would give a positive result in the Xanthoproteic test. The test detects aromatic amino acids and compounds, and adrenaline contains a phenolic group, which reacts with nitric acid to form yellow-colored nitrophenol derivatives. This reaction indicates the presence of these aromatic compounds, thus confirming a positive result.

What is the functional group found in polester?
The functional group found in polyester is an ester group, which is formed by the reaction between an alcohol group and a carboxylic acid group. This ester group is what gives polyester its characteristic properties such as durability and resistance to wrinkles.
Why glysine give negative result in xanthoproteic test?
No because it doesn't contain aromatic group
Why is the xanthoproteic test for phenol negative?
I reckon the answer would be that phenol has a hydroxyl group (-OH) which is bonded to a phenyl ring. It yields the same positive result like tyrosine which has a hydroxyl group bonded to its phenyl ring.
What is the functional groups of benzoic acid?
The functional group of benzoic acid is a carboxylic acid group, which consists of a carbonyl group (C=O) and a hydroxyl group (OH) attached to a benzene ring. This gives benzoic acid its acidic properties.
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.
Is Methyl the functional group that is commonly found in alcohols?
No, methyl is not a functional group commonly found in alcohols. The functional group that is commonly found in alcohols is the hydroxyl group (-OH). Methyl, on the other hand, is a functional group commonly found in compounds called methyl groups (-CH3).
What is the CH3CH2CH2-NH2 functional group?
The functional group is the NH2. It is an amino functional group.
Is vanillin positive in DNPH test?
No, vanillin is not positive in the DNPH (2,4-dinitrophenylhydrazine) test. The DNPH test is used to detect the presence of carbonyl (aldehyde or ketone) functional groups in compounds and vanillin does not contain a carbonyl group.
