What is terephthalamide?
HooC-C6H4-CooH+2NH3=NH4OOC-C6H4-CooNH4--- -2H2O= NH2-CO-C6H4-CO-NH2
What is the structural formula for the compound amine?
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.
What does biuret solution specifically react with to produce a color change?
Copper sulphate gives biuret reagent it's blue colour.
What is NH2 a element or a compound?
Compound.
Suggest possible reaction mechanisms for the reaction of acetone and semicarbazide?
Reaction: CH3C(=O)CH3 + NH2NHC(=O)NH2 --> (CH3)2C=NNHC(=O)NH2 1) N from NH2 acts as the nucleophile, attacks the carbonyl group and changes into a tetrahedral intermediate. Positive charge on NH2, negative charge on oxygen. (CH3)2(O-C)--(NH2)+NHC(=O)NH2 2) oxygen takes the hydrogen from nitrogen through rearrangement because it is more electronegative. (CH3)2(HOC)--(NH)NHC(=O)NH2 3) Acid protonates the alcohol once more to make it a better leaving group. (CH3)2(H2O+C)--(NH)NHC(=O)NH2 4) Nitrogen from NH2 donates its electrons to generate a double bond, bumping off the water molecule and leaving a positive charge on nitrogen. (CH3)2C=NH+NHC(=O)NH2 5) Water pulls off the hydrogen that was still attached to the nitrogen, thus generating the condensation product between acetone and semicarbazide. (CH3)2C=NNHC(=O)NH2
Is NH2 an acid?
No, substances containing the -NH2 group are basic. The NH2- ion is extremely basic.
What are the formulas for the 8 essential amino acids?
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
Which is more basic CH3 or NH2?
NH2- or ammine is its the derivative of ammonia
What is the molecular geometry of NH2-?
NH2- is sp3 hybridized and there is 2 bonding and 2 lone pair of electron,that's why shape of NH2 is angular.
What is the word equation of urea?
NH2 -CO-NH2 Atomic Weight = 60.02 Nitrogen = 46.7% Hydrogen = 6.7% Carbon = 20.0% Oxygen = 26.6
What is the CH3CH2CH2-NH2 functional group?
The functional group is the NH2. It is an amino functional group.
Why does Biurets reagent react with proteins but not amino acids?
Biuret test works for any compound containing two or more of these groups: CO-NH, CO-NH2, CH2-NH2, CNH-NH2, CS-NH2. Amino acids only have one.
What is the nomenclature for a carbonyl group with two amino groups attached?
NH2-CO-NH2 is called urea.
Is -NH2 a polar group?
Yes, the -NH2 group is polar and has weak basic (proton accepting) properties.
What is NH2 and COOH groups called in proteins?
NH2=amino group COOH=Carboxylic acid therefore -oic acid
What is terephthalamide?
HooC-C6H4-CooH+2NH3=NH4OOC-C6H4-CooNH4--- -2H2O= NH2-CO-C6H4-CO-NH2
