IN a recent paper1, one of us has shown that the available data2 on the contours of the infra-red bands of NO 2 are most consistently interpreted by a ring-like structure for the molecule, with the O–N–O angle approximately 60°. The theory of directed valency was employed there to...
Draw the Lewis structure for NO2−. How many bonds and non-bonding pairs are around the central atom? What is the shape of this molecule? Lewis Structure: Lewis Structure is otherwise called electron-dot structure. This gives an id...
The Valence Shell Electron Pair Repulsion or VSEPR model is a model used to account for the correct molecular geometry and shapes of molecule. It is based on the very simple fact that electrons, having negative charges, tend to move away from each...
CHCl3 has a C-Cl bond of 178 pm, and measurements reveal 1.87 D. Calculate the percentage ionic character. Is this a polar molecule? Draw the most plausible Lewis Structure for NO2+, H2SO4 and SO42- Describe the molecule (ClO2)- using three possible Lewis structures, which is the most...

The degree of distortion of the bowl from a regular to an oval shape depends on the type of guest anion. In 51V NMR spectroscopy, all chemical shifts of the host–guest complexes are clearly shifted after guest incorporation. The incorporation reaction rates for OCN−, NO2−, HCO2...
The formation of an intramolecular hydrogen bond results in significantly slower rotational relaxation of the alcohol molecule. The enthalpy differences between the two conformers are found to be 1.52 ± 0.13, 1.57 ± 0.15, 1.53 ± 0.08, 1.06 ± 0.13, and 1.15 ± 0.11 kcal/mol for the ...
