Explain why urea in particular, or amides in general, are much weaker bases than amines. Why the concentrated hydrochloric acid be a poor choice as the acid catalyst for formation of cyclohexene by dehydration of cyclohexanol? Explain why cations such as Fe^{3+} are considered to be acidic....
Why does glucose not undergo Schiff’s base?. Ans: Hint: Schiff’s base: Aldehydes and ketones on treatment with primary aliphatic or aromatic amines in the presence of a trace of acid yields a Schiff’s base.Complete step by step answer:It contains a c.
has proven to be an efficient strategy for coupling 6-halouracil bases to ribose. Furthermore, BSA/NHS serves as a coupling agent for dipeptide synthesis, enabling the coupling reaction between NHS and amines to occur under mild conditions without the need for additional acid/base. The water so...

The carbonyl group of a sugar reacts with the amino group of an amino acid. This reaction yields N-substituted glycosylamine and water. The unstable glycosylamine forms ketosamines through the Amadori rearrangement. The Amadori rearrangement signals the start of the reactions that cause browning. ...
