Why do the molecules that have structures such as H_2C=C=CH_2 or HO-CH=CH_2 are unstable? Why are polar solvents best suited for the SN1 reaction? In capillary electrophoresis, how does switching the mode from positive polarity mode to negative polarity mode affect separation? Does the ...
The sudden shift of electrons causes a temporary polarity, drawing other, temporarily polar atoms having opposite charges. London dispersion forces are weak, but they show their strong influence in long molecules or molecules of high mass. The London dispersion forces are also known as induced ...
Interestingly, severe adipose tissue hypoxia detected by pimonidazole, a nitroimidazole compound that is reduced, thereby binding to sulfhydryl groups of various molecules forming pimonidazole adducts6, has been detected as early as 3 days in mice fed a high-fat diet7. HIF is a heterodimeric ...
1) What causes some molecules to rotate light? Explain in your own words. 2) Discuss your observations in the polarimetry part of the lab. How could you know the molecules are optically active just by looking at the structure? 3) How does the concentrat ...
Over the years chromatography has gained an enviable position in analytical laboratories. You have been introduced to simple concepts on how to read a chromatogram.
DNA strand exchange mediated by a RAD51-ssDNA nucleoprotein filament with polarity opposite to that of RecA. Yeast RAD51 gene functions in genetic recombination and DNA double-strand break repair. In vitro, in the presence of ATP and replication protein A, RAD51 p... P Sung,DL Robberson -...
What causes solubility? Usually, the solubility of a given solute in a given solvent depends on temperature. Solubility tends to equate with rising temperature for several solids dissolved in liquid water. They vibrate faster as water molecules heat up, and are better able to communicate with and...
Water molecules are naturally attracted and stick to each other because of this polarity, forming a hydrogen bond. This hydrogen bond is the reason behind many of water's special properties, such as the fact that it's denser in its liquid state than in its solid state (ice floats on ...
What is the difference between polarity and solubility? At what temperature would the solubility level of 50 g KCL in 100 g H2O? If the solubility of Ag_2CO_3 is 1.3 times 10^{-4} mol / L. What is the K_{sp}? How does the Ksp help to determine solubility? Explain the concept ...
