What is the difference between cryptogams and phanerogams? What is the difference between an ectoparasite and an endoparasite? What is the difference between a chemolithotroph and a chemoheterotroph? What is the main difference between betacyanin and anthocyanin?
For instance,water(H₂O) molecules have the same molar mass as CH₄ molecules. Water begins to boil at 100 °C and methane begins to boil at -161.5 °C. The big difference in boiling points rises from the electronegativities of oxygen and hydrogen creating a dipole in the water molec...
Step-by-Step Solution:1. Definition of Forces: - Dipole-Dipole Forces: These are attractive forces that occur between molecules that have permanent dipoles, meaning they are polar. A permane
Answer and Explanation:1 Polarity is a difference in electrical charge between different parts of the same molecule. This can lead to a dipole moment. The molecule will have... Learn more about this topic: Polar Molecule | Definition, Characteri...
solvent. The dispersion forces used to be found in non-polar substances that are relatively weak and need little energy to break them. But in polar substances, dipole dipole and sometimes hydrogen bonding is found between each molecule. Such forces are much stronger and require more energy to ...
all the elements in group 8 have 8 electrons and completely filled orbitals, that is why the valency of all the elements in this group is zero. difference between valency and oxidation number valency is different from the oxidation number, and it has no sign . thus, the valency of nitrogen...
dipole forces. Thehydrogen bondingstrengthis analyzed on the bases of END and interaction of polymers with reactive clay minerals. Electronegativity difference (END) is most important one because it defines the ability of a molecule to attract electrons towards itself. As much low END, the bond ...

Moreover, the latter authors rule out the possibility of a hydrogen bond between the amide oxygen O4 and the hydroxyl OH5′ which is predicted by CNDO calculations as a stabilisation of the syn form.9,307,308 As a counter-example, we can quote the work by Chow et al.266 on 3-methyl...
Nevertheless, the interpretation of the spectral changes in molecular terms is still limited due to the large number of vibrational modes, uncertainties in the extent of transition-dipole coupling of the separate peptide oscillators and due to the lack of knowledge of the hydrogen-bond strength. In...
