FREE Expert Solution

Hydrolysis of an ester under basic conditions is called saponification.

Proteins are polymers of amino acids joined together by amide linkages. 

In the proton NMR spectra, the N-H proton of primary and secondary amides absorb at 7.5-8.5 ppm. 

A lactone is a cyclic ester in which the carbonyl carbon-heteroatom δ bond is part of a  ring. 

Treatment of nitrites with milder reducing agent, such as DIBAL-H, followed by water will form amine

In the IR spectra, nitrites have an absorption at 2250 cm-1 for the C ≡ N.
