halogen bonding, a specific solvent effect between carbon tetrabromide and oxygen-containing organic solvents, including methanol, ethanol, acetone, dioxane, diethyl ether, and tetrahydrofuran, was found to coexist with the general solvent effect when CBr(4) was over 7.8 x 10(-1...

Bonding in the ground state of C2 is still a matter of controversy, as reasonable arguments may be made for a dicarbon bond order of 2, 3, or 4. Here we report on photoelectron spectra of the C2− anion, measured at a range of wavelengths using a high-resolution photoelectron imaging...
Is the bond formed between carbon and hydrogen ionic, polar covalent, or nonpolar covalent? Explain. For the molecule shown below, draw the most stable conformations and identify any non-bonding interactions. How is hydrogen bonding used to explain the exceedingly high solubility of ammonia gas in...
In early crystal structures of single nucleotides, it was noted that multiple CH···O hydrogen bonds were apparent, especially between phosphate backbone oxygens and the C6 atom of pyrimidines and the C8 atom of purines, and that these interactions were likely stabilized by the anti-...
In doing so, two pairs of electrons are shared between the carbon atom and each of the two oxygen atoms. Two double C=O covalent bonds are formed. We can represent the carbon dioxide molecule formed using either the ‘dot-and-cross’ diagram (shown on the left) or the structural formula...

10(a) and (b), and it was found that the interface between GO and C–S–H was mainly connected through two chemical bonds [96,152]: (1) The hydroxyl functional groups on the GO surface provided non-bridging oxygen sites for water molecules between the C–S–H layers, and hydrogen ...
