Concept explainers
(a)
Interpretation:Benzene, pyridine and pyrimidine should be represented as hybrids of two contributing structures using curved arrows.
Concept Introduction: The representation of a compound by more than one Lewis structure and the actual structure is said to be the hybrid of all these structures, then the compound is said to possess resonance. The actual structure of the compound is the resonance hybrid.
(b)
Interpretation: Benzene, pyridine and pyrimidine should be shown to has an aromatic sextet.
Concept Introduction: The compounds that contain alternate single and double bonds in the chemical structure and are planar that is all the
(c)
Interpretation:The bond angles and shape of pyridine and pyrimidine should be determined.
Concept Introduction: The compounds that contain alternate single and double bonds in the chemical structure and are planar that is all the

- 14 Question (1 point) Disiamylborane adds to a triple bond to give an alkenylborane. Upon oxidation with OH, H2O2, the alkenylborane will form an enol that tautomerizes to an aldehyde. In the first box below, draw the mechanism arrows for the reaction of disiamylborane with the alkyne, and in the last box draw the structure of the aldehyde. 4th attempt Feedback i > 3rd attempt OH, H2O2 i See Periodic Table See Hintarrow_forwardanswer with mechanisms and steps. handwritten please!arrow_forwardHello I need some help with Smartwork. For drawing structure B, I know the correct answer is CH₃B₂, but when I try to type it in, it keeps giving me CH₄BH₃ instead. Do you know how I should write it properly? Should I use a bond or something else?arrow_forward
