Chapter 14.2, Problem 14.10P
Interpretation Introduction

Interpretation:

The way the given compound is prepared using Williamson ether synthesis has to be shown along with reagents, starting alcohols.

Concept Introduction:

Ether are compounds that contain an oxygen atom that is sandwiched between two R groups.  The R groups may be alkyl, vinyl or aryl.

Alcohols when treated with a very strong base undergoes deprotonation to form an alkoxide.  The formed alkoxide ions can acts as a strong nucleophile for the SN2 reaction.  When an alkoxide and an alkyl halide is combined to form an ether, it is known as Williamson ether synthesis.  Usage of primary alkyl halide is recommended for Williamson ether synthesis because the reaction proceeds via SN2 mechanism.  If secondary alkyl halides are used, the elimination reaction will predominate over substitution reaction.  Tertiary alkyl halides cannot be used at all because, it undergoes only SN1 reaction.

The general scheme for Williamson ether synthesis can be given as,

Zeolites: environmental applications.
" 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.
