The pH value required to carry out the imine formation if the pKa value of protonated amine is 9.0 has to be predicted. Concept introduction: Aldehydes and ketones on reaction with amine gives imine, also called as schiff’s base when the nitrogen atom is attached to the alkyl group instead of hydrogen atom. The carbonyl group ( C = O ) of the ketone or aldehyde group is converted into ( C = N ) during imine formation. The general reaction of imine fomrtaion is given as, The imine formation is pH dependent thus the pH of the reaction must be carefully controlled.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
