The most stable and least stable conformations for the given compound has to be drawn in Newman projection. Concept Introduction: Conformation of a single bond in alkane can be visualized using Newman projection. This depicts the groups that are attached to the carbon atoms as they are eclipsed or staggered. Newman projection gives a clear idea about the conformation. This is a 2D representation of the conformers. To draw a Newman projection for a compound, the molecule has to be looked at an angle which gives a clear idea about which groups are present in the carbon atom in which direction. Among the eclipsed and staggered conformations, the staggered conformation is the most stable one. In the staggered conformation also, if the bulky groups are anti to each other means, then that will be the most stable one. In eclipsed conformation, if the two bulky groups are cis to each other, then it will be the least stable one. The various conformation can be obtained by rotating the first carbon atom keeping the second carbon atom fixed.

" is The structure of the bicarbonate (hydrogen carbonate) ion, HCO3-, HCO3 best described as a hybrid of several contributing resonance forms, two of which are shown here. HO :0: :Ö: HO + Bicarbonate is crucial for the control of body pH (for example, blood pH: 7.4). A more self-indulgent use is in baking soda, where it serves as a source of CO2 CO₂ 2 gas, which gives bread and pastry their fluffy constituency. (i) Draw at least one additional resonance form. = (ii) Using curved "electron-pushing" arrows, show how these Lewis structures may be interconverted by movement of electron pairs. (iii) Determine which form or forms will be the major contributor(s) to the real structure of bicarbonate, explaining your answer on the basis of the criteria in Section 1-5.
