Webb21 feb. 2024 · The purpose of this experiment is to analyze compounds containing aldehyde and ketone functional groups with a Fourier-transform Infrared … WebbAldehydes and ketones readily undergo nucleophilic addition reactions due to electronic and structural features of the carbonyl group: • The carbon-oxygen double bond is polarized resulting in a partial positive charge on the carbonyl carbon atom. This makes the carbonyl carbon susceptible to nucleophilic attack.
Webb10 apr. 2024 · Aldehyde oxidoreductases (EC 1.2.99.6) catalyse the reduction of a carboxylate to an aldehyde and the reverse reaction. 8 AORs exhibit a relatively broad substrate spectrum, using short-chain aliphatic aldehydes, branched-chain aliphatic aldehydes and aromatic aldehydes and their corresponding acids (Scheme 2 ). Webb31 aug. 2009 · We performed infrared (FT-IR) spectroscopy measurements to characterize the oximation products (OP) by the disappearance of νC=O (at 1,676 cm -1) and the presence of characteristic broad oxime absorption bands: νO-H near 3,300-3,250 cm -1 ), νC= (N-OH) at 1,645-1,646 cm -1 due to the deformation of the C=N.
