Substituted amino group
WebIf you compare the structure with the amide produced in the reaction with ammonia, the only difference is that one of the hydrogens on the nitrogen has been substituted for a methyl group. This particular compound is N-methylethanamide. The "N" simply shows that the substitution is on the nitrogen atom, and not elsewhere in the molecule. Web21 Jan 2000 · The primary amino group showed two IR absorption bands at 3357-3500 and 3133-3330 cm -1 and a sharp 2H-singlet at δ = 6.92-7.83 ppm in their 1 H-NMR spectra ( cf. [ 6 ]). In the IR spectra, all 3-carbonitriles absorbed at 2181-2217 cm -1 (CN) whereas the methyl 3-carboxylates gave bands in the range 1657-1696 cm -1 for ester carbonyl group.

WebIn examples 4 through 6, oppositely directing groups have an ortho or para-relationship. The major products of electrophilic substitution, as shown, are the sum of the individual group effects. The strongly activating hydroxyl (–OH) and amino (–NH 2) substituents favor dihalogenation in examples 5 and six. Webamide: Any derivative of an oxoacid in which the hydroxyl group has been replaced with an amino or substituted amino group; especially such derivatives of a carboxylic acid, the carboxamides.
