Structures must not be ambiguous, e.g. 1-bromopropane should be shown as CH 3 CH 2 CH 2 Br and not as the molecular formula C 3 H 7 Br which could also represent the isomeric 2-bromopropane. Bonds should be drawn correctly between the relevant atoms.

www.ncert.nic.inAmines can be considered as derivatives of ammonia, obtained by replacement of one, two or all the three hydrogen atoms by alkyl and/or aryl groups. For example: Like ammonia, nitrogen atom of amines is trivalent and carries an unshared pair of electrons. Nitrogen orbitals in amines are therefore, sp3 hybridised and the geometry of amines is ...

www.atsdr.cdc.govrises rapidly on standing because of the deamination of labile amides such as glutamine (Henry 1964); at room temperature, the ammonia content can increase by a factor of two or three in several hours. Therefore, it is important to both keep the specimen cold (on ice) and perform the analysis as soon as possible.
