(a) Interpretation: The explanation for the conversion of A to B is to be stated. Concept introduction: Alkene metathesis generally known as olefin metathesis occurs in the presence of Grubbs catalyst. The ring-closing metathesis (RCM) by Grubbs catalyst occurs if the starting material is diene. This reaction is facilitated under the high-dilution condition as it favors intramolecular metathesis instead of intermolecular metathesis.

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.
