The xanthproteic test gives a positive result when proteins with amino acids carrying aromatic groups are present. Aromatic groups are functional groups consisting of a 6 hydrocarbons with alternating double and single bonds between carbon atoms forming rings.
The hydroxyl group will make the test positive in a xanthoproteic test. This is due to the presence of a phenyl group.
a xanthproteic test gives a positive (yellow) when there is an aromatic group attached to a protein , e.g. tyrosine.
Aromatic group
Tyrosine , phenyl alanine, tryptophan
aromatic group
Yes, it contains carbonyl functional group- aldehyde! :)
The amino functional group.
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.
Hydroxyl group, -OH
It is the amino functional group amine

No because it doesn't contain aromatic group

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).
The functional group is the NH2. It is an amino functional group.
if the alcohol is a primary alcohol the itis oxidized to give aldehyde and if secondary it gives ketone.

Functional groups are responsible for chemical reactions of molecules.
