The nature of the compound formed and the type of reactioninvolved need to be described with given molecular formula. Concept introduction: Electrophiles are electron-deficient species, which has positive or partially positive charge. Lewis acids are electrophiles, which accept electron pair. Nucleophiles are electron-rich species, which has negative or partially negative charge. Lewis bases are nucleophiles, which donate electron pair. Substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a functional group is substituted by any other functional group is called substitution reaction. Elimination reaction: A reaction in which two substituent groups are detached and a double bond is formed is called elimination reaction. Addition reaction: It is the reaction in which unsaturated bonds are converted to saturated molecules by the addition of molecules. The reaction in which hydrogen is added to the compound in the presence of catalyst is known as hydrogenation. The number of moles of hydrogen absorbed will be equal to the number of double bonds. The reaction in which a halide group is removed to form an alkene is called dehydrohalogenation. This reaction in which CO 2 is removed from alkene molecules is called decarboxylation reaction. Piperonal is an acetal, which has an aldehyde moiety in its structure. Acetals are the functional moieties, in which a carbon atom is bonded to two oxygen atoms that are further bonded to alkyl chains. These are formed when alcohols react with carbonyl compounds or dihydropyran in acidic medium or basic medium. The acetal can be cleaved in acidic medium to get back carbonyl compound and alcohol.

a. The structure of the bicarbonate (hydrogen carbonate) ion, HCO3-, HCO3 " is best described as a hybrid of several contributing resonance forms, two of which are shown here. HO :0: HO + :Ö: 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 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.
