How can you tell if a covalent bond is polar or nonpolar? Covalent bonds that are polar have an unequal sharing of a pair of electrons. This would be determined by an electronegativity difference of the two ele
Is the S-S bond expected to be covalent, polar covalent, or ionic? Explain. Is the S-K bond expected to be covalent, polar covalent, or ionic? Explain. Why do polar covalent compounds have higher melting and boiling points than non-polar covalent bonds with the same...
How is it that weak bonds can hold together large macromoles? Explain as simply as possible. How do oxidation states function in covalent bonds? What is a double covalent bond? What forms a polar covalent bond? Does oxygen form ionic or covalent bonds?
Located in the bond between 2 atoms is called localized key. Total number of atoms by the formation of multi-center bond electron delocalization as key. There are also transitional types of keys: one key electronic bias is called polar covalent bond, the bonding electrons provided by the party...
Since the dyes used in a ScCO2-dyeing process are non-polar and natural fibres are polar, the affinity between dyes and textiles is low so physical bonds are weak. Therefore, a dyeing process must be developed for dyeing natural textiles in ScCO2 with reactive dyes that create covalent dye...
(i) Ice has a cage like structure which is created when H(2)O molecules (terahedral in nature) are linked to one another by intermolecular hydrogen bonding. (ii) Water is heavier than ice. (iii) Water has maximum density at 4^(@)C. (iv) The charact
The strong ionic and covalent bonds make ceramics hard and brittle, because the planes of atoms/ions cannot move one through another. For this reason, ceramics and glasses are sensitive to the presence of cracks or other defects during plastic deformation. The ionic and/or covalent nature of ...
Indeed, water is a polar molecule and displays electrostatic properties, forming hydrogen bonds, that confer its capacity of interacting with solutes but also participates in the stability and specificity of protein–protein and protein–DNA interactions [3], [4]. Water is also involved in ...
Alginate presents the polar groups hydroxyl and carboxyl along the chain backbone. The presence of these kinds of groups enables this polymer to ionic and covalent cross‐linking, allowing interactions and linkages between the proteins and polysaccharide chains, and also allows interactions with ...
Are dipole-dipole interactions weak or strong compared to ionic bonds?Question:Are dipole-dipole interactions weak or strong compared to ionic bonds?Polar MoleculesA molecule is said to be polar if bonds between atoms are not equal in all directions. An example is the water molecule. It ...
