Why are amines described as derivatives of ammonia? Explain why most of the salts are soluble in water. Include molecular-level diagrams in the answer. Why are gadolinium salts used as MRI agents? Why do people feel thirsty after eating salty foods? Explain in terms of the colligative property...
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....
Schiff bases are common enzymatic intermediates They are common ligands in coordination chemistry.They were one of the first ligands used for asymmetric catalysis.Schiff’s reagent is rosaniline hydrochloride (whose pink color is decolorized by passing ${ SO }_{ 2 }$ gas). This reagent is ...
Hydroxyl groups (HO-) are poor leaving groupsbecause they’restrong bases. However, if we protonate them (add acid), then we get an oxonium ion (R-OH2+). The leaving group is now H2O – aweak baseand agreat leaving group.The oxonium ion is much better set up to participate in reac...
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. ...
Why are primary aliphatic amines stronger bases than ammonia? View Solution Why methyl amine is a stronger base than ammonia ? View Solution Why ammonia is a stronger base than phosphine? View Solution Which of the following are stronger bases than ammonia ...
Give reasons why the aromatic amines are weaker bases than aliphatic a... 04:06 pKb of aniline is more than that of methylamine. Why? 04:34 Write one chemical test to distinguish between ethylamine and aniline. 03:26 Arrange in increasing order of basic strength: CH3NH2, (CH3)2NH, (CH...
