(a)
Interpretation: To identify the number of amide
Concept introduction: A functional group is an atom or a molecule in the compound which gives the characteristic property to that particular compound. It is the site where the reaction takes place.
(b)
Interpretation: To identify which OH groups are attached to sp3 C-atom and which are attached at sp2 hybridized C-atoms.
Concept introduction: A sp3 hybridization is shown by the C-atoms which are bonded to four substituents and a sp2 carbon atom is bonded to three substituents.
(c)
Interpretation: To identify whether the given compound vancomycin is water soluble or not.
Concept introduction: Hydrogen bonding is seen in those molecules in which a hydrogen atom is bonded to an electronegative atom containing a lone pair like F, N or O. Hydrogen bond is formed when a H atom bonded to the electronegative atom gets attracted towards the lone pair of the electronegative atom present on another molecule. Thus, a molecule can form hydrogen bond with water if it contains electronegative atoms like F, N or O.
(d)
Interpretation: To identify the most acidic proton.
Concept introduction: The most acidic proton is the one present on the functional group which can donate a proton readily and can form salt.
(e)
Interpretation: To identify three functional groups which can form hydrogen bonds.
Concept introduction: Hydrogen bonding is seen in those molecules in which a hydrogen atom is bonded to an electronegative atom containing a lone pair like F, N or O. Hydrogen bond is formed when a H atom bonded to the electronegative atom gets attracted towards the lone pair of the electronegative atom present on another molecule.

- Which of the following will form hydrogen bond with NH3? A.H2O B.CH4 C.CI2 D.CO2arrow_forwardIt has been known for a very long time that lemon juice can mask the "fishy" smell of cooked fish. The "fishy" smell is often due to the presence of amines, such as putrescine, shown below. Lemon juice contains up to 5% citric acid, also shown below. Based on your knowledge amine chemistry and carboxylic acid chemistry, what could be occurring when lemon juice is put on the cooked fish? H₂N NH₂ putrescine, a smelly fish compound HO O O OH 0 OH OH citric acid, a major componant in lemon juice The citric acid undergoes an E2 reaction with the putrescine. The citric acid protonates the putrescine. The citric aicd undergoes and Sn2 reactions with putrescine. The citric acid oxidizes the putrescine. The citric acid hybridizes the putrescine.arrow_forward1. Show how to separate mixture of salt from oil. 2. Explain why alkanes are hydrophobic?arrow_forward
