NettetThe differential equation which represents the approximate motion of the simple gravity pendulum shown in fig. 5 is mlφ¨ +κφ˙ −mgsin(φ)=F(t) , where κis the dissipation term (coming from friction from the air). The problem with this equation is that it is unintegrable. But for small oscillation amplitudes, one The Hofmann rearrangement (Hofmann degradation) is the organic reaction of a primary amide to a primary amine with one fewer carbon atom. The reaction involves oxidation of the nitrogen followed by rearrangement of the carbonyl and nitrogen to give an isocyanate intermediate. The reaction can form … Se mer The reaction of bromine with sodium hydroxide forms sodium hypobromite in situ, which transforms the primary amide into an intermediate isocyanate. The formation of an intermediate nitrene is not possible because it implies … Se mer • In the preparation of anthranilic acid from phthalimide • Nicotinamide is converted into 3-Aminopyridine • The symmetrical structure of α-phenyl propanamide does not change after Hofmann reaction.
