The answer is so general as to be un-answer, with any rigor. It depends entirely upon what is attached in the two sites that are occupied in a specific secondary amine. For relatively general tabulations, see: http://www.chem.wisc.edu/areas/reich/pkatable/ Or try again; a structure can be input using standard abbreviation/shorthands (e.g., Et2NH for diethylamine), or structures can be drawn and translated to SMILES, via: cactus.nci.nih.gov/services/translate/ All for now.

What is the distinguishing test between primay secondary and tertiary amine?
HINSBERG TEST IS THE DISTINGUISH TEST BETWEEN PRIMARY SECONDARY TERTIARY AMINE
What is pKa value of aminoacids?
The pKa values of Amino acids depends on its side chain. However, the protonated amine group (NH3+) tends to have a pKa greater than 8.8, whereas the carboxylic acid (COOH) tends to have a pKa of 1.8 - 2.8. If you keep your amino acid at a pH between this value, you will likely have a Zwitter ion.
Is there any amino acid having secondary amino group in its structure?
The amino acid proline is the only amino acid that has a secondary amine functional group. This is because proline is a cyclic amino acid that links the 3-carbon R-group back to the amine group, resulting in a secondary amine.
What is the secondary amine with the molecular formula C3H9N?
This compound is N-methylethylamine.
What is tyrosine charge at pH 4?
we can't tell the charge of lysine at 4.5 because the PKa is not given. we can only know what charge it carries with the PKa value on carboxyl group or amine group.And to know the charge remember when PH is less than PKa it is always 0 while when PH is higher than PKa it is always -1 on carboxyl group. For the amine group it is always +1 as the PKa is always higher than the PH. so for example we have PKa1 2.19 PKa 5.2 for caboxyl group and 9.67 For amino group. to deter mine the charge is on pka1 the charge -1 because PH4.5 is higher than the pka,while on pka 2 the charge is 0 as PH 4.5 is lower than PKa.while for amine group it is + 1 because PKa is higher than PH4.5 so there the charge on lysine will be calculated -1+0+1=0. that's how i understand it
What is an aminyl?
An aminyl is a radical derived from a primary amine or secondary amine.

How do you determine the pKa value of an organic compound for HPLC method?
the organic compound three kind normal, acid and basic compound for acid compound the pKa from 3 to 5, normal pKa around 7 and basic compound more than 7 also you can know the kind of organic compound from structure that you can see acidic or basic grope like carboxylic acid or amine.
What is the name of symbol NH?
NH may be:- a part of secondary amine- nitrogen monohydride molecule
Is methanamine a secondary amine?
Methanamine is actually considered a primary amine. This is because only one of the hydrogen atoms in the ammonia molecule has been replaced. It is one of the simplest compounds for amines.
What functional group is amphetamine in?
It contains a Secondary Amine group as well as a Secondary Hydroxyl group. There is also a benzene ring which is not considered a functional group.
What is an arylalkylamine?
An arylalkylamine is a secondary or tertiary amine which has both an alkyl and an aryl group connected to the nitrogen atom.
What is reductive amination reaction?
It's a reaction to add a single alkyl group to a primary amine. It involves creating an imine from the primary amine and an aldehyde and then reducing it to a secondary amine. Other methods of alkylation of amines would add more than one alkyl group.
