The given fatty acid has to be classified on the basis of omega classification system. Concept introduction: The position of double bonds in unsaturated fatty acids is denoted by the Greek lowercase letter omega ( ω ). The position of the double bond is specified relative to the methyl end or non-carboxyl end of the fatty acid carbon chain.

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.
