In drawing the Lewis structure of an ion, the following steps are followed. 1. Determine the total valence electrons of the elements in the ions. Do not forget to account for the charge. 2. Identify the central
The interactions between Lewis acid YCF3(Y = Cl, Br, I) and pyridine and para-substituted pyridine are closed-shell and noncovalent interactions. On the one hand, when the halogen bond acceptor XC5H4N is fixed, with the increase of halogen atomic number, the strength of halogen bond ...
Answer and Explanation:1 To find the molecules in which both the bonds are multiple bonds. The Lewis structure of the given molecules are; As we can see, the only...
UiO-66 MOFs were prepared with 2-nitroterephthalate as linker and decanoic acid as modulator. The decanoic acid present in the MOF structure is chemically bound and influences the porous and catalytic properties, including surface area and pore volume, Lewis acidity, and hydrophobicity. The samples...
Additionally, an empty 2p orbital of B in the ring plane allows the formation of a donor–acceptor interaction with electron-rich atoms (Lewis basic sites) of the ortho substituent. Nitro substitution in the 2-position is associated with a small positive energetic effect (1.12 kcal/mol), in ...
albicans strains, showing significant antifungal activity compared to the standard drug fluconazole, especially for derivatives prepared from aromatic amines substituted with nitro groups in the para and meta positions (structure (a) in Figure 2). On the other hand, Al-Azmi recently synthesized a ...
