It has been suggested that banana (bent) double bonds are a superior description to the \(\sigma -\pi\) structure which is usually offered in chemical textbooks14, and this has been taken as evidence that the Kekulé description is more authentic than the delocalised, MO picture15,16,17,...

What is the lewis structure for GeCl_6-2, determine the hybridization on the center atom and what are the sigma and pi bonds? Which of the following molecules have Lewis structures with lone pairs of electrons on the center atom? A. OF_2 B. CCl_4 C. CO_2 D. All of...
Remarkable progress has been achieved in the realm of protein structure prediction from sequence data. Some prediction techniques use machine learning in concert with molecular dynamics or Monte Carlo1,2,3,4. These generate an ensemble of structures. AlphaFold, which leads the way in the prediction...
Connecting pi-chromophores by sigma-P-P bonds: new type of assemblies exhibiting sigma-pi-conjugation. To study the ability of sigma-P-P skeleton to mediate interaction between pi-chromophores, 1,1'-biphospholes bearing phenyl or thienyl substituents at the 2,2' and 5,5'-position have been...

Include all lone pairs of electrons and fDraw an octet-rule Lewis structure for CO32-. State which orbitals or hybrids on C and O overlap to make each valence bond, state each bond type (sigma or pi bond), and state the total bond order between eac...
Langya Henipavirus (LayV) infection is an emerging zoonotic disease that has been causing respiratory symptoms in China since 2019. For virus entry, LayV’s genome encodes the fusion protein F and the attachment glycoprotein G. However, the structural an
Several ionizations occur in 14-22 eV region, making a definitive assignment difficult, but the molecular orbitals are mostly C-H and C-N sigma bonds that offer little structural information. The more relevant ionizations are of the highest occupied molecular orbitals in the 10-13 eV region, ...
