The crosslinking reaction occurred at a higher rate in a polar solvent, such as dimethylformamide, than in a nonpolar one, such as toluene, and was affected by the nature of the chlorine-containing polymer. Some of the polymers crosslinked even at room temperature. The chain-extending reactio...
Is a bond formed between potassium and bromine ionic, polar covalent, or nonpolar covalent? Explain. Sodium chloride (NaCl) exhibits predominantly ionic bonding. The Na^+ and Cl^- ions have electron structures that are identical to which two inert gases? Cations and anions are able to form...
This compound is soluble in polar solvents such as water and methanol. However, it is insoluble in nonpolar solvents like hexane. POTASSIUM PHENYLTRIFLUOROBORATE is considered to be relatively safe to handle, but as with any chemical, proper precautions should be taken to avoid ingestion, skin ...
hydrophilicity and/or the amphipathic nature of the residues involved. For example, negatively charged amino acids include aspartic acid and glutamic acid; positively charged amino acids include lysine and arginine; amino acids with uncharged polar head groups or nonpolar head groups having similar hydr...
These families include amino acids with basic side chains (e.g., lysine, arginine, histidine), acidic side chains (e.g., aspartic acid, glutamic acid), uncharged polar side chains (e.g., glycine, asparagine, glutamine, serine, threonine, tyrosine, cysteine), nonpolar side chains (e.g.,...
