Question
1. 10 points. State differenc ring structure and having an oxygen atom e one major difference between having a nitrogen atom in a in that structure 2. 10 points. Would you expect amines to be more soluble or less soluble in water than alcohols with comparable molecular weight? why 3. 10 points. Will an amine be more soluble in açidic or basic solutions? Why ? 4. 10 points. What characteristic of amines allows them to form water soluble salts ? 5. 10 points. Describe two features of carboxylic acid molecules that give these acids very high boiling points.Explanation / Answer
1) Nitrogen ring atom have one lone pair whereas oxygen ring atom has two lone pair thus oxygen ring is more stable than nitrogen ring due to resonance thus oxygen ring has low melting point than low boiling point than nitrogen ring atom
2)Amine is more soluble in water than alcohol
H-OH bond is more polar than R-OH thus more hydrogen bonding of H-OH than R-OH thus amine is more soluble in water than alcohol
3)Amine is basic in nature thus it will be more soluble in acidic solvent as compared to basic solvent
4)Since nitrogen has lone pair it can share its lone pair to form coordinate complexes which allow amine to form more water soluble salts
