(a)
Interpretation:
With the help of curved arrows the conversion of structure (a) to (b) should be drawn.
Concept Introduction:
?-bond of double bond gets shifted in resonance.
(b)
Interpretation:
Comparison of Lewis structure of oxygen between structure (b) and hydroxyl group is to be determined.
Concept Introduction:
In the hydroxide ion there is negative charge or on oxygen atom and there is also negative charge in given structure (b).
(c)
Interpretation:
Lewis dot structure of ammonium ion and nitrogen in the structure (b) is to be compared.
Concept Introduction:
Nitrogen can donates it lone pair to form coordinate bond.
(d)
Interpretation:
H-N-H bond angle in structure (a) is to be determined.
Concept Introduction:
In amide group carbonyl group is attached to −NH2 group.
(e)
Interpretation:
Bond angle of H-N-H in structure (b) is to be determined.
Concept Introduction:
In amide group carbonyl group is attached to −NH2 group.
(f)
Interpretation:
Relative importance of the resonance hybrid on the basis of given information is to be written.
Concept Introduction:
Proteins can be described as polyamides. In amide group carbonyl group is attached to −NH2 group.
