(b) The molecular structure is square planar with the lone pairs directly across from one another. WebIn extraction procedures, the choice of the extracting solvent will determine what type of components will be extracted—this is also true in regard to cork by-products: when using polar solvents, such as methanol, ethanol and water, the compounds extracted will be of phenolic nature; however, when using solvents of low polarity, such as DCM ...

WebThe carbon-nitrogen bond is generally considered polar covalent because the electronegativity difference is sufficiently high (~0.5). So the entire molecule is engaging in covalent bonding because all the atoms involved have similar electronegativities because they are all nonmetals, however some are polar and one is nonpolar. Hope that helps.
