(a)
Interpretation:The resonance structures of bicarbonate ion needs to be drawn with the use of electron pushing arrows and the form that will be the major contributor to the real structure of bicarbonate ion needs to be determined.
Concept Introduction:VSEPR theory stands as Valence Shell Electron Pair Repulsion Theory. It helps to predict the molecular shape or geometry of the molecule with the help of the number of bond pair or lone pair present in it. According to VSEPR theory, the presence of lone pair on the central atom of molecule causes deviation from standard molecular geometry.
The resonance is the phenomenon in which if all the properties cannot explain by one structure, it can be shown in two or more structures by the shifting of pi bonds or lone pair but there is no change in sigma bond and position of atoms.

Select the most plausible Lewis structure of the ion. Explain.arrow_forward(b) The Murchison meteorite that landed in Australia in 1969 contained 92 different amino acids, including 21 found in Earth organism A skeleton structure (single bond only) of one of these extraterrestrial amino acids is shown below. Draw a Lewis structure, and identify any atoms having a nonzero formal charge. H3N. C ČH2 ČH3 (c) Draw the orbital diagrams and Lewis symbols to depict the formation of Na* and CI ions from the atoms. Give the formula of the compound formed. (d) The predicted bond length for HF is 109 pm (the sum of the covalent radii of H, 37 pm and F, 72 pm), however the actual bond length for HF is shorter (92 pm). It was observed that the difference between predicted and actual bond lengths becomes smaller going down the halogen group from HF to HI Describe these observationsarrow_forward2. Below are drawn four possible isomers (partial Lewis structures with different atomic connectivity) for an anion with the molecular formula C₂H4NO. 10 A B D "TOTT" raptor H H -0- (a) First, add enough electrons as either lone pairs or r bonds to give an overall negative charge. Show all lone pairs in each completed Lewis structure, and show any atomic formal charges that result. (b) Then, for each isomer, consider if other resonance structures can contribute. Since this is an anion, look for a strong electron donor with an adjacent electron acceptor. For each additional resonance structure you draw (some isomers may have more than one additional RS, some may have none), circle the electron pairs in the original Lewis structure which have moved, and draw a curved arrow depicting the motion required to create the new RS. If you have colored pens, color coding your electrons pairs is nice (but not required).arrow_forward

- There are two main types of covalent bond breakage. In ho-molytic breakage , each atom in the bond gets one of the shared electrons. In some cases, the electronega-tivity of adjacent atoms affects the bond energy. In heterolytic breakage, one atom gets both electrons and the other gets none;thus, a cation and an anion form. (a) Why is the C−C bond in H₃C−CF₃(423 kJ/mol) strongerthan that in H₃C−CH₃(376 kJ/mol)?(b) Use bond energy and any other data to calculate the heat ofreaction for the heterolytic cleavage of O₂.arrow_forwardWrite resonance forms that describe the distribution of electrons in each of these molecules or ions.
