It stands for an amino group.
Copper sulphate gives biuret reagent it's blue colour.
-NH2
There are two possibillities:1-aminopropaan CH2(NH2 )CH2CH32-aminopropaan CH3CH(NH2)CH3
AnswerBasic amine formula is A-NH2 , A-NHR, or A-NR2; (in which A is an alkyl or aryl group, singly bonded, may be substituted) Primary will have no R group like phenylamine (C6H5)-NH2Secondary amine will have on R groupTertiary will have two.
When -NH2 and -COOH replace hydrogen atoms in a molecule, it forms an amino group (-NH2) and a carboxyl group (-COOH) respectively. These two functional groups are key components of amino acids, which are the building blocks of proteins.
The N in -NH2 stands for nitrogen. The -NH2 group consists of a nitrogen atom bonded to two hydrogen atoms.
Valine: HO2CCH(NH2)CH(CH3)2 Tryptophan: C11H12N2O2 Threonine: HO2CCH(NH2)CH(OH)CH3 Phenylalanine: HO2CCH(NH2)CH2C6H5 Methionine: HO2CCH(NH2)CH2CH2SCH3 Lysine: HO2CCH(NH2)(CH2)4NH2 Leucine: HO2CCH(NH2)CH2CH(CH3)2 Isoleucine: HO2CCH(NH2)CH(CH3)CH2CH3
No, substances containing the -NH2 group are basic. The NH2- ion is extremely basic.
NH2- is sp3 hybridized and there is 2 bonding and 2 lone pair of electron,that's why shape of NH2 is angular.
The functional group is the NH2. It is an amino functional group.
NH2 -CO-NH2 Atomic Weight = 60.02 Nitrogen = 46.7% Hydrogen = 6.7% Carbon = 20.0% Oxygen = 26.6
Aniline is the name of benzene with an NH2 group attached.
NH2-CO-NH2 is called urea.
Yes, NH2 can form hydrogen bonds with other molecules.
NH2 is an electron-donating group in organic chemistry.
NH2=amino group COOH=Carboxylic acid therefore -oic acid
